How to spell indispensable

indispensable

Indispensable is spelled I-N-D-I-S-P-E-N-S-A-B-L-E.

Not indispensible.

Why is indispensable easy to misspell?

-able or -ible

The word indispensable ends -able, and the misspelling indispensible writes -ible. Dispense stands as a word on its own, and a stem like that usually takes -able.

-able and -ible sound identical, so the ending has to be learned rather than heard. -able is the commoner of the two, and usually follows a part that can stand as a word on its own.

in + dispense + able · dispense drops its e before -able
