elect: [15] To elect somebody is literally to ‘choose them out’ of a range of possibilities. The word comes from ēlectus, the past participle of Latin ēligere ‘pick out, select’. This was a compound verb formed from the prefix ex- ‘out’ and legere ‘gather, choose’ (source also of English collect, neglect, and select and, from its secondary meaning ‘read’, legible and lecture).

The notion of ‘choosing by ballot’ is the oldest of the verb’s senses in English. A person who may be ‘elected’ or ‘chosen’ is eligible [15] (an acquisition via French from the late Latin derivative ēligibilis). And someone who has been ‘picked out’ from the crowd is a member of the élite [18] (a borrowing of the feminine form of the past participle of French élire ‘elect’).

Also closely related is elegant.
