Did you know?

The meaning of many English words equals the sum of their parts, and coalesce is a fitting example. The word unites the prefix co- (“together”) and the Latin verb alescere, meaning “to grow.” Coalesce is one of a number of English verbs (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, such as a political ideology, a fan-following, or (perish the thought) a Portuguese man-of-war, the body of which includes three types of zooids.
