'lyricize' originates from Modern English, specifically formed from the noun 'lyric' + the verb-forming suffix '-ize' (from Greek '-izein' via Latin/French), where 'lyric' is ultimately from Greek 'lyrikos' relating to 'lyra' (the lyre) and '-ize' meant 'to make' or 'to render'.

'lyric' comes from Greek 'lyrikos' (related to 'lyra', the lyre), passed into Latin as 'lyricus' and into Middle/Modern English as 'lyric'. The productive suffix '-ize' comes from Greek/Latin/French verb-forming endings; combining them produced the verb 'lyricize' in Modern English, from which 'lyricized' is derived.

Initially formed to mean 'to make into a lyric or to render in a lyrical manner'; over time the core meaning has remained largely the same, describing conversion into or treatment with lyrical/poetic qualities.
