Midsection → It is formed from "mid-" (meaning middle) and "section" (from Latin "sectio", meaning a cutting or division). The word "midsection" refers to the middle part of something, particularly the body.
Think of the 'middle' ('mid-') part that is 'cut' or 'divided' ('section') from the rest — that's what midsection means.
