lucubrate (English)
Where does "lucubrate" come from?
The English verb 'lucubrate', meaning to work or study at night, was first attested in 1623[1]. It was borrowed from the Latin 'lūcubrātus', the perfect passive participle of 'lūcubrō', which means to work by candlelight[1] or to compose by lamplight[2]. This Latin verb ultimately derives from 'lūx' meaning 'light'[1], tracing back through Proto-Italic to the Proto-Indo-European root '*lewk-'[3][4].
