means Small invertebrate animals with a three-part body, six legs, and usually wings, forming the most numerous class of creatures on the planet.

from From Latin 'insectum,' meaning 'cut into,' a translation of the Greek 'entomon' (the root behind 'entomology'). Both names point to the same striking feature: the body looks notched or divided into segments, as if neatly sliced. The Latin comes from 'insecare' — 'in' (into) plus 'secare' (to cut), a cousin of words like 'section' and 'dissect.' So every bug carries the ancient observation that it seems chopped into parts.
