Etymology: Overfunctioning is a plain formation: the prefix "over-" attached to "function," so that the stem means to perform a role or task beyond what is normal or healthy. In everyday English the word is used of people who take on far more responsibility than their situation calls for, often to keep a family, team or relationship running smoothly. The "over-" prefix has long carried the sense of excess, as in "overeat" or "overwork," and "function" in its older sense of a duty or office gives the compound its meaning. The word thus combines two familiar elements into a single description of excessive duty-taking, with the "-ing" ending marking it as a participle or gerund form of the verb "overfunction."
