Changable vs. Changeable: Correct Spelling

If you are looking for the correct spelling, here it is: Changeable is the only correct spelling in standard English.

The word requires the "e" from the root word "change" to remain before adding the suffix "-able" (C-H-A-N-G-E-A-B-L-E). Spelling it as "changable" 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.

Notice how the root "change" ends in a "ge", and the suffix "-able" begins with an "a". The "e" is kept in the middle to stop the "a" from making the "g" hard.

To understand why the "e" is kept, we have to look at English consonant rules. The letter "g" can make two sounds: a hard sound (as in "go" or "gag") and a soft sound (as in "giraffe" or "gem"). The rule is that "g" is usually soft when followed by an "e", "i", or "y".

If you drop the "e" from "change" and add "-able", you get "changable". Visually, this suggests the "g" is followed by an "a", which would dictate a hard "g" sound, making the word look like it should be pronounced "CHANG-guh-bul" (rhyming with "bang"). To preserve the soft "g" (the "j" sound), the "e" must be retained as a buffer.

This exception applies to all words ending in a soft "ce" or "ge" sound. For example, "notice" becomes "noticeable" (not "noticable"), and "manage" becomes "manageable" (not "managable"). Noah Webster and other spelling reformers left these words alone because altering them would fundamentally change the pronunciation of the root word.
