Root Explanation

Osculum is derived from the Latin word "osculum" (meaning little mouth or kiss). The root "os" (meaning mouth) is combined with the diminutive suffix "-culum" (indicating smallness). Thus, osculum refers to a small mouth or a kiss, symbolizing a gentle or affectionate touch.

Memory Tip

Think of a 'little mouth' ('osculum') representing a kiss, which is a gentle and affectionate gesture.
