Why "ConvertIBLE" and not "ConvertABLE" [duplicate]
Why do almost all words that are "able" written like:
- Comparable
- Disposable
- Doable
- Writable
Except for the word "Convertible"?
Can someone explain this to me or are there no rules tied to this? (I was just curious).
Solution 1:
It stems from the Latin term "convertibilis", which means changeable. The term "convertible" is Old French, dating back to the 13th-14th century. I'd imagine they kept the i because it was more familiar with the original term.
