feature: [14] Feature comes ultimately from Latin factūra, a derivative of the verb facere ‘do, make’ which meant literally ‘making, formation’. Elements of this original sense remained when the word reached English via Old French faiture – when John Dymmok wrote in 1600 of ‘horses of a fine feature’, for example, he was referring to their shape or general conformation – but already a semantic narrowing down to the ‘way in which the face is shaped’ had taken place.

This meaning was then distributed, as it were, to the individual components of the face, and hence (in the 17th century) to any distinctive or characteristic part.
