'bucolicism' originates from English, specifically formed from the adjective 'bucolic' and the suffix '-ism', where 'bucolic' ultimately traces to Greek 'boukolikos' and the suffix '-ism' meant 'practice or characteristic'.

'bucolic' changed from Latin 'bucolicus', which came from Greek 'boukolikos' (from 'boukolos' meaning 'herdsman' and 'bous' meaning 'ox' or 'cow'), and eventually modern English formed 'bucolicism' by adding the suffix '-ism'.

Initially, it meant 'of or relating to herdsmen or pastoral life', but over time it evolved into its current meaning of 'the pastoral or idealized qualities of rural life'.
