go get

[Vladv1]

I 've heard many natives use a bare infinitive after the verb "go". Go get the pizza!
Does it work when "go" is in the second or the third form, in other words, can I say " I went get pizza". Can any verb other than get be used this way?

No.

 

[Vladv1]

No.

Can I use "go get' after all modals? He should got get a water. He might have gone get a water?

I've heard many natives use a bare infinitive after the verb "go". Go get the pizza!

That's really short for "go to/and get the pizza".

That's been answered above.

Can any verb other than get be used this way?

I don't know what you mean, but you may hear expressions like:
Go figure!
or
Go whistle!
You can look them up if you're interested in what they mean.

Can I use "go get' after all modals? He should got get a drink/bottle of water.

That has several flaws:
1- "Should" should be followed by the base form of the verb.
2- "Water" is typically uncountable.
3- To answer your question: no you can't. You would need to insert "to" or "and":
"He should go and/to get a drink/bottle of water".

He might have gone get a water?

Again, no. The correct form would be:
He might have gone to get a bottle/drink of water.
or
He might have gone and got ("gotten" in AmE) a bottle/drink of water.

I decided to go get a pizza. Is it correct?

"I must go see the concert" is incorrect?

 

[teechar]

I decided to go get a pizza. Is it correct?

Yes, it is.

"I must go see the concert" is incorrect?

That doesn't sound natural to me. You may encounter something like "I must go see the dentist soon", which is informal and in which "go see" acts as a single unit indicating an urgency of some kind.

 

[jutfrank]

I decided to go get a pizza.

I must go see the concert.

I think these are just about defensible, if you take them as casual, ellipted forms of the pattern 'go and (do something)'.

Can any verb other than get be used this way?

Come is sometimes used that way, though it may perhaps be a bit more informal than the usage with go:

Come help me with this.​

I think of Stanley Kubrick's horror film The Shining. The young British girl twins say, "Come and play with us, Danny, forever, and ever, and ever" rather than "Come play with us"; but Jack, the American, shouts at his wife, Wendy, "Go check it out!"

Interestingly, help is itself sometimes followed directly by another verb, though the fine-tuned analysis would be a bit different.

Come help set the table.​
