Origin of lexicon
historical usage of lexicon
English lexicon was first used in the sense “dictionary, wordbook,” and usually referred to dictionaries of Greek and the culturally important Semitic languages (Hebrew, Syriac, Aramaic, Arabic). Dictionaries of these particular languages were traditionally written in Latin, and since Latin had no native word for dictionary, lexicon was the word generally used.
Our English word dictionary comes from Medieval Latin dictiōnārium, the neuter form of dictiōnārius ( liber ) “word (book)”—that is, “a phrase book, a beginner’s textbook (of Latin).”
