Suitable, appropriate, or well-fitted for a particular purpose or situation.
From Latin 'en-' (into) + 'aptus' (fitted, suitable). An archaic or rare English formation using the Latin root 'apt' meaning naturally fitted or skilled.
This word is mostly forgotten, but 'apt' itself comes from the same Latin root meaning 'fitted'—and when you add 'en-' it emphasizes that something is naturally suited to its task, like an 'enaptly' chosen word.
