Invaginate is formed from "in-" (meaning into) and "vaginare" (meaning to sheath or enclose). The word describes the process of folding or sheathing something inward.
Think of something being 'enclosed' or 'sheathed' ('vaginare') 'into' ('in-') itself, which helps you remember that invaginate means to fold inward.
