The expression “hold up” has several different meanings. One is a robbery. A man with a gun may say, “This is a hold up. Give me your money.” Another meaning is to delay. A driver late for work may tell his boss, “I was held up by heavy traffic.” Someone who was robbed on the way to work might say, “Sorry, boss, I was held up by a hold up.”

Still another meaning of the expression is for a story to be considered true after an investigation. The same driver late for work could say, “My boss did not believe a hold up held me up. But the police confirmed what I said, so my story held up.”

“Hold on” is another expression. Often it means wait or stop. As you leave for school, your brother may say, “Hold on, you forgot your book.”

“Hold on” is used to ask a telephone caller to wait and not hang up his telephone. If you call a library to ask for a book, the librarian might say, “Hold on while I look for it.”

Our final expression is “hold the line.” That means to keep a problem or situation from getting worse -- to hold steady. For example, the president may say he will “hold the line on taxes.” He means there will be no increase in taxes.
