Correct spelling

believable

Correct spelling, explanation: the word believable is created by adding the adjective suffix able to the base word believe. In the process the ending e in believe is removed. There are instances of words where ea stands together (changeable), but generally if it’s possible it’s more intuitive to let go of the e and this is what happens in most cases similar to this one.

Definition of believable:
Adjective
1. Realistic, possible to believe, plausible
His explanation was not perfect but it was at least believable.
They felt that his story was not quite believable.


Incorrect spelling

believeable

Incorrect spelling, explanation: the form believeable might seem like it makes sense based on the original word and the suffix, but it’s not correct simply because the less silent letters – the easier it is to write and more intuitive to read. Considering the fact that the e at the end of believe is silent anyway, it can be deleted.
