We can think about the W-ever words semantically as the 'W' word + the quantifier 'any'. The trick to understanding these terms is to realize that they apply to any single one of the referents, and at the same time refer to all of the referents.
• Whatever - Anything (This could also be everything) • Whenever - Any time (This could also be 'every time') • Wherever - Any 'where' (Anywhere or everywhere). • Whoever - Anyone (Any person or every person, or sometimes used to refer to a person unknown to the speaker) • Whichever - Any 'which' (Choice between a group or set). • However - Any 'way' (In any manner or way, regardless of how).
