Etymology: Subproblem is a plain formation: the prefix "sub-", meaning "under" or "below" in Latin, attached to "problem." The sense is simple. A subproblem is a smaller problem sitting beneath a larger one, and solving the main challenge usually means solving each of these first. The base word has a more interesting past. In ancient Greek, "próblēma" meant something put forward, a task or a question set for discussion, built from "probállō," "to throw forward." Latin borrowed it as "problēma," and it passed through Middle French "probleme" into English, where it was used for a question proposed for solution. The sense of "difficulty" grew from that idea of something thrown in your path to be dealt with. Because "sub-" simply attaches to this existing word, the compound follows the meaning of "problem" closely, with the prefix narrowing it to the parts beneath a larger whole.

Synonyms: subissues, secondary problems
