However, some verbs which can act as main verbs are "delexicalised" - they have no individual meaning other than indicating "perform the action indicated by the noun". In English, do, have, take and make are all delexicalised verbs.
- She had lunch
- We took a break
- I made a mistake
- He did the shopping
Some of these verbs can of course also be used with lexical meaning :
have = possess : She has a lovely house.
take = seize hold of : She took a book off the shelf.
