Etymology: "Underbolster" is a rare, technical-sounding verb built from ordinary English parts: "under," meaning beneath, and "bolster," the old word for a long cushion or pillow, used for propping up a pillow or support. "Bolster" itself comes from Old English "bolster," a cushion or pillow, and its figurative sense of giving support or reinforcement developed from that literal use of padding something up. Adding "under-" gives the idea of support placed beneath a load. The form "underbolsters" is the third-person singular present of the verb, so it means "underbolster" as used with "he," "she," or "it." Its noun use, "underbolster," is a derivative of the same verb, and the word is attested mainly in technical and specialist writing rather than everyday speech, so its exact first recorded date is uncertain.
