Wheresoever → It is formed from "where" (from Old English "hwær", meaning at what place) and "soever" (from Old English "swa" meaning so or in this way, combined with "ever" meaning at any time). The word "wheresoever" means at any place or wherever.
Think of 'where' as asking about a place and 'soever' as meaning 'in any way' — together, they help you remember that 'wheresoever' refers to any place.
