Withdrawal is when you take something out, like making a withdrawal from your bank account.
When you announced you were no longer running for president, your withdrawal from the race disappointed your many supporters. Withdrawal is also used to describe the painful experience that results when you stop taking an addictive drug (when you "take it out" of your system). The state of being emotionally detached is called withdrawal. If a country terminates an agreement like a treaty, that's a withdrawal too. Remember that withdrawal ends in "wal" and not just "wl."
