'acute-leaved' originates from the combination of 'acute,' meaning 'sharp or pointed,' and 'leaved,' referring to the leaves of a plant.

'Acute' comes from the Latin word 'acutus,' meaning 'sharp,' and 'leaved' is derived from the Old English 'lēaf,' meaning 'leaf.'

Initially, it meant 'having sharp leaves,' and this meaning has remained consistent in modern usage.
