Elect
late Middle English: from Latin elect- ‘picked out’, from the verb eligere, from e- (variant of ex- ) ‘out’ + legere ‘to pick’.
wiktionary
Borrowed from Latin ēlēctus, past participle of ēligō(“to pick out, choose, elect”), from ē-(“out”) + legō(“to pick out, pick, gather, collect, etc.”); see legend.
Cognate to eclectic, which is via Ancient Greek rather than Latin, hence prefix ἐκ(ek), rather than e- (from ex).
