Invigorate → It is formed from "in-" (meaning into or within) and "vigorare" (from Latin "vigor", meaning strength or energy). The word "invigorate" means to give strength or energy to something or someone, essentially bringing energy into them.
Think of bringing 'strength' ('vigor') 'into' ('in-') something — that's why invigorate means to energize or refresh.
