A fixed expression is a form of expression that has taken on a more specific meaning than the words themselves. It is the standard way of expressing a concept or an idea; it is something we ordinarily say in certain situations.
Examples include:
- Pleased to meet you
- All of a sudden
- On the other hand
- More trouble than it’s worth
- Neither here nor there
Examples include:
- A can of worms (a complicated problem)
- A chip of the old block (a child with similar characteristics to one of their parents)
- To be out for the count (to be sleeping peacefully)
- Rub someone the wrong way (annoy or bother someone)
- Pull someone’s leg (tease someone by trying to make them believe something that is not true)
