Unlockable?

English is a difficult and strange language.

Take the word unlockable. What does it mean?

Does it mean something that is not locked and can't be locked?

Or does it mean something that is already locked, and can be unlocked.

Consider the phrases "Unlockable door" and "Unlockable content"...

And then consider the word unbreakable instead and the same lines of thought.

The confusion occurs because of the dual affixes with contradictory meanings.

unlockable vs unlockable

A strange case of doublethink in modern English.
