Etymology: Botanists needed a name for the fruiting stage of a flower cluster, and they built it by swapping one part of an existing word. "Inflorescence" describes the flowering cluster, and "infructescence" replaces the "flor" (flower) with "fruct" (fruit), so the term names the same cluster after its flowers have given way to fruit. The swap reflects the botanical idea that the cluster is one structure passing through two stages. The "fruct" comes from Latin "fructus," meaning fruit or produce, and the ending "-escence" comes from a Latin verb pattern meaning "to become" or "to begin to be," so the word literally suggests a cluster becoming fruitful. The "in-" is the same prefix as in "inflorescence," where it means "into" or "upon" rather than "not," which helps explain why the two words mirror each other so closely.

Synonyms: fruiting, fruit cluster, fruit set, fruit development
