The expression ‘the matter’ or ‘the matter with’ can be used after words like something, anything, nothing and what. It means something like ‘wrong with’.
- Something is the matter with Maria. She doesn’t talk to anyone. (= Something is wrong with Maria.)
- Is anything the matter? (= Is anything wrong?)
- Something is the matter with my car. It doesn’t start.
- What’s the matter with you today? (= What is wrong with you today?)

We sometimes use ‘there’ as a preparatory subject for something, anything and nothing.
