I have lunched

[hamoodee]

I heard my seven-year-old son , who is learning English as his second languge, saying " I have just lunched"
He means he has just had his lunch. My question is: Can lunch be used as a verb as well as a noun?

[Anglika]

It is a recognised verb.

Ladies who lunch are sometimes busy professional women.
We lunched at the Hilton yesterday.

Yes it is possible to use Lunch as a verb, e.g.
# I am lunching with Rafiq.

This is usually used when you have lunch formally in a returant with a guest.
# I will be lunching with a client.

Do you know that the verb "GO" is used as a noun?

As others have said, "lunch" can be a verb. But it is usually a verb in the context of adult society. So I would guess that this 7-yr-old was making a 'mistake' (using the verb in an inappropriate context), but just happening - accidentally - to use a possible verb. He was also, as native speakers do, creating a verb out of a known noun. More or less any noun, as they say, can be verbed.

Yes , but in diffrent meaning . I read or heard a sentence " You can not eat an elephant in one go ."

Well, I was curious about this myself. So I checked out dictionary.com and found these examples of 'go' being used as a noun:

47.the act of going: the come and go of the seasons.
48.energy, spirit, or animation: a man with a lot of go.
49.a try at something; attempt: to have a go at winning the prize.
50.a successful accomplishment; success: to make a go of a new business.
51.Informal. a business agreement; deal; bargain: Thirty dollars? It's a go.
52.Informal. approval or permission, as to undertake or begin something: The boss gave us the go on the new project.
53.Boxing. a bout: the main go.

Hope this helps.
