How to pronounce "Pacas" in American and British English.
1. Stressing the second syllable (pa-KAS) instead of the first (PA-cas). 2. Pronouncing the final 's' as /s/ instead of the voiced /z/. 3. Pronouncing the first vowel as a long 'ay' (PAY-cas) instead of /ɑː/ or /æ/. 4. Adding an extra syllable: 'pa-ca-has' (three syllables). 5. Confusing the plural 'pacas' with the singular 'paca' in writing.
American Pronunciation
In American English, 'pacas' is pronounced /ˈpɑːkəz/ (PAH-kuhz) or /ˈpækəz/ (PA-kuhz). The first syllable carries the stress and contains either an open back unrounded /ɑ/ (as in 'father') or a near-open front /æ/ (as in 'cat,' depending on the speaker). The second syllable is an unstressed schwa /ə/. The final /z/ marks the plural.
Say it like this: PAH-kuhz.
British Pronunciation
In British English, 'pacas' is pronounced /ˈpækəz/ (PA-kuhz), essentially identical to the American variant with the /æ/ vowel. Some British speakers may use the back /ɑː/ vowel as well, mirroring the American /ˈpɑːkəz/ pronunciation. The stress pattern is the same: first-syllable stress, schwa in the second, final /z/.
Say it like this: PAH-kuhz.
IPA
The IPA transcription is /ˈpɑːkəz/ or /ˈpækəz/. The symbol /ˈ/ marks primary stress on the first syllable. The /ɑː/ or /æ/ is the stressed vowel; /ə/ is the schwa (neutral 'uh'); and /z/ is the voiced alveolar fricative that marks the plural ending. The word has two syllables total.
Syllables
'Pacas' has two syllables: PA·cas. The stress falls on the first syllable. The second syllable is unstressed and reduced to a schwa.
Stress
The primary stress is on the first syllable: PA-cas. The second syllable is unstressed and shortened to a schwa. This is the typical English pattern for two-syllable nouns borrowed from other languages.
Pronunciation Tips
- Stress the first syllable: PA-cas. Do not stress the second syllable (pa-KAS).
- Use the open back vowel /ɑː/ (as in 'father') or the front /æ/ (as in 'cat') for the first syllable.
- Reduce the second syllable to a soft schwa /ə/ (an 'uh' sound), not a full 'ah' or 'ay.'
- Pronounce the final 's' as a voiced /z/, like the 'z' in 'buzz,' not as a voiceless /s/.
- Practice with rhyming words: alpacas, maracas, tobaccos.
- Do not pronounce it as 'pay-cas' (with a long 'ay' sound).
- Avoid adding an extra syllable; 'pacas' has two syllables, not three.
- Listen to recordings of natural history documentaries about Neotropical wildlife to hear the word in context.
Word Origin
Where does "Pacas" come from, and how did it evolve?
Etymology
The word 'paca' comes from the Tupi language family of Brazil. The original Tupi word 'pák' (or 'paka') referred to the animal itself. The word entered European languages through Portuguese and Spanish colonists in the 16th century, was adapted to 'paca' in both languages, and was borrowed into English in the 17th century. The plural 'pacas' was formed in English by adding the standard English plural suffix '-s' to the borrowed singular.
History
European naturalists first encountered pacas in Brazil in the 1500s and quickly adopted the indigenous Tupi name. The word appears in Portuguese and Spanish colonial records by the late 1500s and entered English in the 1600s through travel writing and natural history texts. The plural 'pacas' followed naturally with the standard English -s plural ending. By the 18th century, 'paca' was established in scientific literature, and Linnaeus catalogued the species in his Systema Naturae (1766) as Mus paca, later reclassified into the genus Cuniculus.
Language Origin
'Paca' is a loanword from Tupi, an indigenous South American language family spoken in Brazil and neighboring regions. The Tupi-Guaraní language family is one of the most widespread indigenous language families of South America. The word is not native English; it is a borrowed term that has been fully naturalized into English usage.
How Meaning Changed Over Time
The meaning of 'paca' has remained remarkably stable since its introduction to English: the large spotted rodent Cuniculus paca. What has changed is the scientific classification. Formerly placed in the genus Agouti (giving the older scientific name Agouti paca), pacas were reclassified into their own genus Cuniculus based on molecular and morphological evidence. The common English name 'paca' has remained unchanged throughout this taxonomic reshuffling. The plural 'pacas' simply follows the standard English pluralization pattern.
Interesting Historical Facts
Pacas belong to the family Cuniculidae (formerly Agoutidae) and are classified in the order Rodentia. They are among the largest rodents in the Americas, second only to the capybara. Indigenous Tupi, Guaraní, and other South American peoples have hunted pacas for thousands of years, and the animal remains an important protein source throughout much of its range. Despite the older scientific name Agouti paca, pacas are not closely related to true agoutis (genus Dasyprocta), which belong to a different family.
Did You Know: The word 'paca' comes from the Tupi language of Brazil, where it was 'pák.' European colonists adopted the indigenous name in the 1500s, and English borrowed it in the 1600s. The plural 'pacas' simply adds the standard English '-s.'

How to Pronounce
Step-by-step pronunciation guide for English learners.
To pronounce "Pacas" like a native American English speaker, follow these simple steps.
Step 1: The First Syllable
Start with the stressed vowel /ɑː/ or /æ/. For /ɑː/, open your mouth wide as if saying 'ah' in 'father.' For /æ/, drop your jaw as if saying 'a' in 'cat.' Either is acceptable in American English; British English favors /æ/.
Step 2: The Consonant Bridge
Close the first syllable with a clean /k/ sound, as in 'kit' and 'back.' There is no gap between the vowel and the consonant; the word flows as one unit.
Step 3: The Second Syllable
The second syllable is an unstressed schwa /ə/ followed by the voiced /z/ sound of the plural ending. Keep it short and soft, like the ending of 'maracas' or 'alpacas.' Do not say 'kayz' (rhyming with 'maze'); it should be 'kuhz.'
Step 4: Put It Together
Say the full word: PA-cas. Stress the first syllable; soften the second. Practice with rhyming words: alpacas, maracas, tobaccos. The word should sound like 'PAH-kuhz' or 'PA-kuhz.'

Meaning Explained
A beginner-friendly explanation of what "Pacas" means.
Picture a tropical rainforest at night. The air is thick and humid; the calls of frogs and insects fill the dark. At the edge of a stream, a large reddish-brown shape emerges from the undergrowth-a paca. Its fur is marked with rows of white spots along the sides, its head is large and square, and its tail is barely visible. It bends to drink, then moves on, foraging for fallen fruit. If you saw several of these animals together, you would be looking at pacas.
Pacas are an everyday fact of life in the Neotropics-from southern Mexico to northern Argentina. They are hunted for their meat (often called 'the pork of the rainforest'), studied by biologists for their role in seed dispersal, and sometimes kept in captivity for breeding programs. They are shy, nocturnal, and rarely seen by casual visitors, which makes a sighting of wild pacas a memorable experience for any tropical traveler.
A Simple Diagram
Source: A single paca (Cuniculus paca) lives in the rainforest near water.
Group: When two or more are observed together, they are 'pacas.' ↓
Singular vs plural: Singular: 'one paca.' Plural: 'several pacas.' The plural adds '-s' to the singular.
Usage: ↓ 'Pacas are nocturnal herbivores.' 'We saw three pacas at the river.'
The Key Idea
'Pacas' is simply the plural of 'paca.' It names more than one of these large, spotted, rainforest-dwelling rodents. Like 'cats,' 'dogs,' or 'rabbits,' the plural form allows speakers and writers to refer to the species in general or to multiple individual animals.
Student Tip: Picture a large rodent with reddish-brown spotted fur, a big square head, and almost no tail. That's a paca. Two or more of them are 'pacas.' They live in the rainforests of Central and South America.

When NOT to Use
Situations where "Pacas" sounds wrong, awkward, or confusing.
1. Do Not Confuse with 'Alpacas'
An alpaca is a domesticated South American camelid (a relative of the llama). A paca is a rodent. Despite the similar-sounding names, they are completely different animals. 'Alpacas' is far more common in English than 'pacas.'
2. Do Not Confuse with 'Pacas' (food)
In some Spanish-speaking countries, 'paca' can also refer to a bale of hay or cotton. In English, however, 'paca' almost always refers to the rodent.
3. Do Not Confuse with 'Packas' or 'Pakas'
These are not standard English words; they may be misspellings of 'pacas' or 'packs.'
4. Do Not Use It as a Singular
'Pacas' is plural. Use 'paca' for a single animal. Saying 'a pacas' is incorrect.
5. Do Not Confuse with 'Agoutis'
Although pacas were once classified in the genus Agouti, true agoutis (Dasyprocta) are a different animal-smaller, with different fur and habits. 'Pacas' and 'agoutis' refer to different animals.
6. Do Not Use It for Old World Animals
Pacas are strictly a New World (Neotropical) species. They are not found in Africa, Asia, or Australia.
Common Mistake: Do not confuse 'pacas' with 'alpacas.' An alpaca is a domesticated South American camelid (relative of the llama). A paca is a rodent. Despite the similar names, they are completely different animals.

Quick Tip: The strongest modifiers for 'pacas' in English are 'wild,' 'captive,' 'breeding,' 'nocturnal,' and 'spotted.' Numbers and quantifiers also work freely: 'three pacas,' 'several pacas,' 'many pacas.'
Grammar Notes
Key grammar rules for using "Pacas" correctly.
Rule 1: 'Pacas' Is the Plural of 'Paca'
'Pacas' is the standard English plural of 'paca.' It refers to two or more individual animals of the species Cuniculus paca. The singular is 'paca'; the plural is 'pacas.'
Rule 2: Use Plural Verb Agreement with 'Pacas'
Because 'pacas' is plural, it takes a plural verb: 'Pacas are nocturnal,' not 'Pacas is nocturnal.' The singular 'paca' takes a singular verb: 'The paca is nocturnal.'
Rule 3: 'Pacas' Takes No Apostrophe for the Plural
The plural of 'paca' is 'pacas,' not 'paca's.' Apostrophes are used for possessives ('the paca's fur,' 'the pacas' burrows'), not for ordinary plurals.
Rule 4: Use Numbers and Quantifiers Freely
Because 'pacas' is a countable plural, it can be modified by numbers and quantifiers: 'three pacas,' 'several pacas,' 'many pacas,' 'a few pacas,' 'dozens of pacas.'
Rule 5: Watch Out for the Singular as Modifier
When used as a noun modifier, the singular 'paca' is generally preferred even when referring to the species in general: 'paca habitat,' 'paca meat,' 'paca population.' This is the same pattern as 'dog food' (not 'dogs food').
Grammar Tip: 'Pacas' is the standard plural of 'paca,' formed by adding '-s.' It takes a plural verb, takes no apostrophe for the plural, and is fully countable: 'three pacas,' 'dozens of pacas.'
Spelling Notes
Common misspellings and typing mistakes.
Correct Spelling
The correct spelling is pacas.
Common Misspellings
paca's (apostrophe for plural), pacas (correct), pakas (k for c), packas (adding 'ck'), paças (Portuguese cedilla), pacus (u for a), pacases (adding -es), paccas (doubling c), pacahs (h after a), paacas (extra a)
Common Typing Mistakes
pacaa (extra 'a'), pacas (correct), paxas (x for c), oacas (o for p), pacas (correct), paas (missing 'c'), pscar (typing s for p, r for s), pacqd (q for a, d for s)
Common Mistake: Do not write 'paca's' for the plural. The apostrophe is for possessives ('the paca's fur'), not for ordinary plurals. The correct plural is simply 'pacas.'
Pronunciation Tips
Helpful tips for ESL learners.
- Stress the first syllable: PA-cas. Do not stress the second syllable (pa-KAS).
- Use the open back vowel /ɑː/ (as in 'father') or the front /æ/ (as in 'cat') for the first syllable.
- Reduce the second syllable to a soft schwa /ə/ (an 'uh' sound), not a full 'ah' or 'ay.'
- Pronounce the final 's' as a voiced /z/, like the 'z' in 'buzz,' not as a voiceless /s/.
- Practice with rhyming words: alpacas, maracas, tobaccos.
- Do not pronounce it as 'pay-cas' (with a long 'ay' sound).
- Avoid adding an extra syllable; 'pacas' has two syllables, not three.
- Listen to recordings of natural history documentaries about Neotropical wildlife to hear the word in context.
ESL Tip: Many learners stress the wrong syllable, saying 'pa-KAS' instead of 'PA-cas.' Always stress the first syllable, and pronounce the final 's' as a voiced /z/ (like 'buzz'), not a voiceless /s/.

Word Comparison
How "Pacas" differs from similar words.
Pacas vs Capybaras
Capybaras (Hydrochoerus hydrochaeris) are larger than pacas, with uniform brown fur and a more social, diurnal lifestyle. Pacas are smaller, have spotted fur, are nocturnal, and are more solitary. Both are large Neotropical rodents, but they belong to different families (Cuniculidae for pacas, Caviidae for capybaras).
| Feature | Pacas | Capybaras |
|---|---|---|
| Size | Up to 12 kg (26 lb) | Up to 65 kg (143 lb) |
| Fur | Reddish-brown with white spots | Uniform brown or reddish-brown |
| Activity | Nocturnal, solitary | Diurnal, social (groups of 10-20) |
| Habitat | Forest near water | Wetlands, savannas, forests near water |
Pacas vs Agoutis
Agoutis (genus Dasyprocta) are smaller, more slender rodents with uniform brown fur and longer legs. Pacas are larger, stouter, and have distinctive spotted fur. The two were once confused in taxonomy (paca's former genus was 'Agouti'), but they belong to different families.
| Feature | Pacas | Agoutis |
|---|---|---|
| Size | Up to 12 kg (26 lb) | Up to 4 kg (9 lb) |
| Fur | Reddish-brown with white spots | Uniform brown or reddish |
| Build | Stout, large head | Slender, long legs |
| Family | Cuniculidae | Dasyproctidae |
Pacas vs Pacaranas
Pacaranas (Dinomys branickii) are rare, large South American rodents with a similar-sounding name. Despite the name similarity, pacaranas belong to a different family (Dinomyidae) and have a distinctive striped-and-spotted pattern different from the paca's spotted sides. Pacas are far more common and widely distributed.
Pacas vs Guinea Pigs
Guinea pigs (Cavia porcellus) are small domesticated caviomorph rodents, weighing about 1 kg. Pacas are wild, weigh up to 12 kg, and are not domesticated. Both belong to the caviomorph group, but pacas are in the family Cuniculidae while guinea pigs are in Caviidae.
Pacas vs Coypus
Coypus (Myocastor coypus), also called nutrias, are large semi-aquatic rodents weighing up to 10 kg. Like pacas, they are large Neotropical rodents, but they have round tails (vs the paca's barely visible tail), webbed hind feet, and uniform brown fur. Coypus are also more aquatic than pacas.
Writing Tip: When choosing between 'pacas,' 'capybaras,' and 'agoutis,' remember: pacas are spotted and stout; capybaras are larger and uniform brown; agoutis are smaller and more slender. All three are Neotropical rodents.

Frequently Asked Questions
Quick answers to common questions.
What does the word 'pacas' mean?
'Pacas' is the plural of 'paca,' a large Central and South American rodent of the species Cuniculus paca. Pacas are distinguished by their reddish-brown fur with white spots along the sides, their stout bodies, their large square heads, and their very short tails. They are nocturnal, solitary, and live in burrows near water in tropical forests from southern Mexico to northern Argentina. The plural 'pacas' refers to two or more individual animals.
What kind of animal is a paca?
A paca is a large rodent in the family Cuniculidae, scientifically known as Cuniculus paca. It is one of the largest rodents in the Americas, second only to the capybara, weighing up to 12 kilograms (about 26 pounds). Pacas are nocturnal herbivores with reddish-brown spotted fur, a stout body, a large square head, and a barely visible tail. They are native to the tropical forests of Central and South America.
Where do pacas live?
Pacas are native to the Neotropics, ranging from southern Mexico through Central America to northern Argentina. They live in tropical rainforests and other forested habitats near water, since they are excellent swimmers and often escape predators by diving into rivers and streams. They dig burrows in riverbanks or use natural cavities among tree roots.
How do you pronounce 'pacas'?
In American English, 'pacas' is pronounced /ˈpɑːkəz/ (PAH-kuhz) or /ˈpækəz/ (PA-kuhz). The first syllable carries the stress; the second is an unstressed schwa. The final 's' is a voiced /z/ sound (like the 'z' in 'buzz'), not a voiceless /s.' Practice with rhyming words: alpacas, maracas, tobaccos.
Are pacas related to capybaras?
Yes, distantly. Both pacas and capybaras are large Neotropical rodents in the infraorder Caviomorpha, but they belong to different families. Pacas are in the family Cuniculidae (genus Cuniculus), while capybaras are in the family Caviidae (genus Hydrochoerus). They share a common ancestor but have evolved separately for millions of years.
Are pacas endangered?
No, pacas are currently classified as 'Least Concern' by the IUCN Red List, meaning they are not considered endangered. However, they face pressure from habitat loss due to deforestation and from hunting in some areas. In regions of heavy deforestation, paca populations have declined significantly, even though the species as a whole remains secure.
Are pacas nocturnal or diurnal?
Pacas are nocturnal, meaning they are active at night and sleep during the day. They forage after dark for fallen fruit, seeds, tubers, and nuts, and they spend the daylight hours in their burrows. This nocturnal habit is why pacas are rarely seen by casual visitors to the rainforest, despite being relatively common throughout their range.
What do pacas eat?
Pacas are herbivores. Their diet consists mainly of fallen fruit, seeds, nuts, tubers, and other plant material they find on the forest floor at night. They are important seed dispersers in tropical forests, since they often carry seeds away from the parent tree before eating them. They will also raid agricultural crops like sugarcane, corn, and cassava when their forest habitat borders farmland.
Is 'pacas' the plural of 'paca'?
Yes. 'Pacas' is the standard English plural of 'paca.' It is formed by adding the regular English plural suffix '-s' to the singular 'paca.' The plural is used for two or more individual animals: 'one paca, two pacas.' It takes a plural verb: 'Pacas are nocturnal.'
Why are pacas hunted?
Pacas are hunted primarily for their meat, which is widely considered a delicacy throughout their range and is often called 'the pork of the rainforest' for its tender, pork-like flavor. Indigenous communities in Central and South America have hunted pacas for thousands of years, and the practice continues today in many rural areas. Pacas are also sometimes hunted for crop protection, since they can damage sugarcane, corn, and other crops.
