"Coalesce" unites the prefix "co-" ("together") and the Latin verb "alescere," meaning "to grow." (The words "adolescent" and "adult" also grew from "alescere.") "Coalesce," which first appeared in English in the mid-17th century, is one of a number of verbs in English (along with "mix," "commingle," "merge," and "amalgamate") that refer to the act of combining parts into a whole. In particular, "coalesce" usually implies the merging of similar parts to form a cohesive unit.
