What does ternate mean?
Ternate is a specialized botanical adjective describing parts arranged in threes. It most often refers to leaves or leaflets that grow in whorls, with three leaves or leaflets arising at or around each node on a stem. The term can also be applied more broadly to flowers or other plant structures grouped in threes. In ordinary writing, ternate is less common than the plainer phrase “in whorls of three,” but it is useful in botanical descriptions because it is concise and precise. Its unusual sound can make it memorable, yet its meaning is straightforward: it comes from Latin and essentially indicates a threefold arrangement. While it may appear in descriptions of plant families and botanical keys, ternate is generally unsuitable when describing ordinary objects or people merely occurring in groups of three.

Where does ternate come from?
Ternate comes from Latin ternātus, meaning “arranged in threes,” derived from ternī, “three each.” The word entered English through botanical usage and follows the same Latin numerical family as ternary and ternity. Its meaning narrowed to a technical botanical description of plant parts arranged in groups or whorls of three.
