## Etymology
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.
