Origin

The noun is derived from Middle English cluster (“bunch, cluster, spray; compact body or mass, ball”) [and other forms], from Old English cluster, clyster (“cluster, bunch, branch”), from Proto-Germanic *klas-, *klus- (“to clump, lump together”) (possibly from Proto-Indo-European *gel- (“to ball up; to clench; to amass”)) + *-þrą (suffix forming nouns denoting an instrument or tool). The English word is probably a doublet of clot. The verb is derived from the noun. Cognates * Dutch klister (“cluster”) (dialectal) * Icelandic klasi (“cluster; bunch of grapes”) * Low German Kluuster (“cluster”) * Swedish kluster (“cluster”)
