Capable of being extended or drawn out; having the property of extension or stretchability.
From Latin extensilis, derived from extendere. The '-ile' suffix means 'tending to' or 'capable of,' as seen in words like 'tactile' or 'projectile'.
The '-ile' suffix is less common than '-able' or '-ible' in modern English, which makes 'extensile' sound a bit archaic or scientific, though it's still used in specialized fields like materials engineering!
