The vocabulary used by or known to an individual. (Also called lexical knowledge.)
A set of vocabulary specific to a certain subject.
Origin
Through Middle French or directly from New Latin lexicon, from Byzantine Greek λεξικόν ("a lexicon, a dictionary"), ellipsis from Ancient Greek, from λεξικός, from λέξις, from λέγειν, ultimately from Proto-Indo-European *leǵ- ("to gather, collect").
Attested at least since 1583 (in William Fulke's A Defense of the Sincere and True Translations of the Holy Scriptures into the English tongue) in the sense 'a dictionary of a classical language'.
