Offered by many hotels as a service, wake-up calls are literally telephone calls that are intended to wake you up at a predetermined time in the morning. Idiomatically speaking, a wake-up call is ❛an occurrence or event that makes you realize that you have to deal with a problem or change a situation❜. For example:
Last week’s English exam was the wake-up call that Luigi needed. He now knows that he is going to have to study harder to pass the course.
The election loss was a wake-up call for the political party. It was very clear that it would have to re-evaluate its policies and strategies.
Thank you for the wake-up call. I now know what I have to do to solve the problem.
In other words, a wake-up call is a ❛warning❜ that you are going to have to take action in regard to a problem or situation. Some good examples of how to use the English idiom wake-up call can be found in these recent headlines:
