A hard plate on the back of an arthropod segment, part of its outer covering.
The tergite of the insect was shiny and well-defined, showing its segmented structure.
Tergite comes from the Latin word 'tergere' (meaning to wipe or clean) and the suffix '-ite' (often used to denote a component or part). The word 'tergite' refers to a part that is involved in the act of wiping or cleaning.
Think of 'wiping' ('tergere') something clean, and remember that 'tergite' refers to a part involved in that cleaning action.
