Common Mistakes

Do not confuse pack as a verb meaning 'put into a container' with pack meaning 'crowd together' or 'carry on one's person'.
Do not use group words like clique or coterie as synonyms for the criminal noun sense.
Do not mix the travel verb backpack with the noun pack meaning a bundle or package.
Pack can mean very different things in different contexts, so the sentence usually tells you which sense is intended.
