'plumule' originates from Latin, specifically the word 'plumula,' where 'pluma' meant 'feather' or 'down.'

'plumula' transformed into the French word 'plumule,' and eventually became the modern English word 'plumule.'

Initially, it meant 'a small feather or down,' but over time it evolved into its current meaning of 'the first bud of a plant embryo.'
