Embroil comes from French embrouiller ('to entangle, confuse'), from en- ('in') + brouiller ('to mix, mingle, confuse'), of uncertain ultimate origin. Morphologically, the form is compositional: en- marks part of the visible structure, while the remaining element supplies the lexical base. In present use, it is used as a verb meaning "to involve someone deeply in conflict or difficulty", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes derivatives such as embroilment and embroiled and related forms such as broil, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include French embrouiller, keeping the history tied to concrete forms rather than a loose resemblance. Its semantic neighborhood is marked by entangle, involve, implicate, and enmesh on one side and contrasts such as disentangle, extricate, and disengage on the other, locating the modern specialization without adding a new origin story.
