Able to be changed or altered; capable of transformation.
From 'change' (from Old Norse 'skipta') plus '-able' suffix (from Latin 'habilis'). The '-able' suffix transforms verbs into adjectives meaning 'capable of being' or 'worthy of.'
This spelling (without the 'e' before 'able') appears in older English texts but lost out to 'changeable' during standardization—it's a perfect example of how simpler spelling sometimes loses to more complex variants for no logical reason.
