Sharp or pointed; having a sharp end or tip.
From Latin 'acuatus,' derived from 'acus' meaning 'needle' or 'sharp point.' This is related to 'acute' but was used more specifically for physical sharpness.
'Acuate' and 'acute' come from the same Latin root, but 'acute' evolved to mean both literally sharp and figuratively keen or serious—'acuate' stayed more literal, which is why it's used in botany to describe leaves with pointed tips.
