Thanks.

Sentence (3) is grammatical if it is used to express two separate events, but if used to express a single event then it's ungrammatical in terms of the semantics of English.

What do these mean?
1. It's ungrammatical in terms of the semantics of English.
2. It's ungrammatical in terms of semantics of English. (If this is incorrect, why?)

Well, I believe "go look" has the structure main verb + bare infinitive, wherein 'look' functions as a noun, as the object of 'go'.

Let's go DO (infinitive; object of 'go'; noun)
EX: Let's go shop (object)
EX: Let's go look. (object)

Let's go DOING (present participle; object of 'go'; gerund)
Let's go shopping (object)

Dear Casiopea,

Thank you very much for your explanation. Now I see.

Have a nice weekend.

(2) Let's go look. (one event 'go look')
(3)*Let's go and look. (two separate events used to express a single event)
