Same Words, Different Meanings

I occasionally get into a muddle when talking with English people.  We use a lot of the same words, but they have different meanings sometimes.  For example, we were invited for tea at Anna's classmate's house.  I thought that meant like afternoon tea, but after being asked whether we are vegetarian, I had to inquire further, and found that tea meant dinner.
