- Useable: correct but less common

The Origin of Usable or Useable
The word usable comes from the verb use, which has roots in Old French and Latin. English formed the adjective by adding a suffix that means “able to be.”
The basic idea is:
use + -able = usable
The spelling useable developed because writers sometimes kept the full spelling of the base word use before adding -able.
This creates two possible forms:
- use + able → useable
- use + able → usable
English often drops a final silent e before a suffix beginning with a vowel. This is why usable follows a common spelling pattern.
For example:
- use → usable
- cure → curable
- move → movable
However, English spelling is not completely consistent. Some words keep the final e, which helps explain why useable also exists.
Today, both forms are recognized, but usable has become the standard choice for most modern writing.
British English vs American English Spelling
