Etymology: "Understrap" is a plain compound: the prefix "under-" (meaning beneath or lower in position) joined to "strap," a narrow band of leather, cloth, or metal used for fastening or binding. Put together, the word names a secondary strap placed beneath a main one, which is the sense the meaning gives: a supporting strap that adds stability or keeps the primary strap in line. The pattern is a familiar English one. "Under-" has been used for centuries to form nouns and verbs for lower or subordinate parts, such as "undergarment" and "underpin," so "understrap" follows the same logic. Its meaning comes straight from its two parts, with nothing surprising in its development.
