"a lyric poem" (one suggestive of music or fit to be sung), 1580s, from French lyrique "short poem expressing personal emotion," from Latin lyricus "of or for the lyre," from Greek lyrikos "singing to the lyre," from lyra (see lyre). Meaning "words of a popular song" is first recorded 1876. Related: lyrics.
word-forming element meaning "one who does or makes," also used to indicate adherence to a certain doctrine or custom, from French -iste and directly from Latin -ista (source also of Spanish, Portuguese, Italian -ista), from Greek agent-noun ending -istes, which is from -is-, ending of the stem of verbs in -izein, + agential suffix -tes.
Variant -ister (as in chorister, barrister) is from Old French -istre, on false analogy of ministre. Variant -ista is from Spanish, popularized in American English 1970s by names of Latin-American revolutionary movements.
