Etymology: "Collocational" is a plain formation: the English noun "collocation," meaning the habitual co-occurrence of words, with the adjective-forming suffix "-al" added to it. "Collocation" itself descends from the Latin "collocatio," a noun built on "collocare," meaning to place or arrange together, from "com-" ("together") and "locare" ("to place"), the same root that gives English "locate." The Latin sense of arranging things side by side explains the modern meaning. Words are not just placed near each other in a sentence; certain pairings, such as "heavy rain" or "strong tea," recur so reliably that a speaker expects them. The adjective applies to anything relating to those expected pairings, and it is mainly used in linguistics and lexicography.
