A small leaf or leaflet, especially one of the individual leaflets that make up a compound leaf.
From Latin 'foliolum,' the diminutive form of 'folium' (leaf), used in botany to distinguish small leaflets from larger full leaves.
Each tiny piece of a fern frond is a foliole—and ferns have thousands of them, creating an almost feathery appearance that lets them thrive in shady forest floors where big leaves would be too heavy.
