IPA: /ˈdaʊnˌwɑrp/
KK: /daʊnˌwɑrp/
A part of the Earth's crust that curves or bends downwards.
The geologist studied the downwarp to understand the geological history of the area.
Downwarp → It is formed from "down" (from Old English "dūn", meaning downward or lower) and "warp" (from Old English "weorpan", meaning to throw or to bend). The word "downwarp" describes the action of bending or throwing something downward.
Think of something being 'thrown down' ('warp' means to throw or bend, and 'down' indicates direction) — that's why downwarp means to bend downward.
