Did I Loose You?

Online recently I discovered a new example of word confusion: expand and expend. The first means to increase, the latter means to decrease as in to spend or use up. An exhortation to "expend your contacts" was not an incentive to sign up for a business networking service. Other commonly confused words include:

affect and effect (both as nouns and verbs)

rap and wrap

lie and lay (as verbs)

accept and except

allusion and illusion and delusion

censure and censor

compose and comprise

imply and infer

founder and flounder

loose and lose
