catch a break
1. To obtain or receive a convenient, beneficial, and/or lucky opportunity. I finally caught a break when a big Hollywood producer asked me to audition for a part in the movie.
2. To receive special treatment or a favorable deal, especially regarding a reduced price on something. Tenants in the city center will be catching a break on rental prices when the city council introduces a new rent-control scheme next year. You'll catch a break on your car insurance if you don't get in any accidents while you're driving.
3. To obtain new information leading toward a solution to a given problem. The detectives finally caught a break when an anonymous caller tipped them off to the kidnapper's location.
4. To get relief from some difficulty or problem(s). We're hoping to catch a break from the drought with a little bit of rainfall this weekend. First ,my car breaks down and then I lose my keys to the apartment—I just can't catch a break today!
