The Quick Answer
If you are looking for the correct spelling, here it is: Colonel is the only correct spelling in standard English.
The word requires a single "l" and an "n" in the middle (C-O-L-O-N-E-L). Spelling it as "collonel" with a double "l" is universally considered a grammatical error in professional, academic, and casual writing. If you struggle with this word, you are not alone—it is one of the most frequently misspelled words in the American English language due to its bizarre pronunciation.
Correct Spelling
The definitive way to write this word.
C-O-L-O-N-E-L
Take note of the single "l" at the beginning and the "n" in the middle. This is the only accepted spelling in both American and British English dictionaries.
Common Misspellings
The most frequent errors writers make.
Collonel
Doubling the first "l" incorrectly. The most common error.
Kernel
Spelling it exactly as it sounds. A frequent phonetic error.
Colonal
Using an "a" instead of an "e". A severe spelling error.
Why Is This Word Misspelled?
The linguistic breakdown of a notorious spelling trap.
The confusion stems from a massive clash between English spelling rules and English pronunciation. When we speak the word "colonel," we pronounce it as "kernel," completely ignoring the first "l" and sounding like it has an "r." Because our brains associate the spoken word with a completely different set of letters, our hands naturally want to type "kernel" or add an extra "l" to make sense of the spelling.
The Phonetic Trap
Spoken: KER-nul. The word is pronounced like "kernel," tricking the ear into wanting to use an "r" or double the "l" to justify the spelling.
The Etymological Rule
Written: C-O-L-O-N-E-L. The Italian root dictates a single "l" and an "n," regardless of how it sounds when spoken.
Correct Spelling Breakdown
Analyzing the word syllable by syllable.
co
Prefix (from Latin 'com-')
lo
Root part 1 (from Italian 'colonna' meaning column)
nel
Root part 2 (diminutive suffix)
colonel
Complete Word (noun form)
Notice how the spelling "colonel" directly relates to the word "column," reflecting the military formation, even though the pronunciation went a completely different route.
Spelling Pattern
The Latin assimilation rule at work.
To understand why this word looks nothing like it sounds, we have to look at Italian and French. The word comes from the Italian 'colonnello,' the commander of a 'colonna' (column) of soldiers. It is built from the Latin 'columna,' meaning "column."
When the word entered English in the 16th century, it came through the French 'coronel,' which is why we pronounce it with an "r" instead of the first "l." However, English writers soon decided to adopt the spelling closer to the original Italian 'colonnello,' spelling it "colonel" but keeping the French "r" pronunciation.
Noah Webster, the father of American English spelling, intentionally simplified many words, but he left "colonel" alone because its Italian roots required the "l" and "n" to retain the structural connection to "column," the unit of troops the officer commanded.

How to Remember the Spelling
Memory tricks & mnemonics to lock it in forever.

The word "colon" is perfectly spelled inside "colonel" (C-O-L-O-N). Just add an "el" to the end. Think of a colonel having a colon.
2. The "One L" Trick
There is only one "l" in the middle. Think: A colonel leads a single line (column) of troops, so there is only one "l" in the middle.
3. The "Kernel" Association
Even though it sounds like "kernel," remember it's spelled like "column" with an "el" ending. A colonel commands a column.
4. The "Lo-Nel" Breakdown
Break it into two parts: "Lo" and "nel." Say it out loud as "Co-Lo-Nel" to force yourself to remember the 'l' and 'n' placement.
