What is the meaning of 'have' in #1?
'Have' has a lot of meaning. Does 'have' mean 'drink'? What is the difference of the four sentences?

#2 makes no sense.

All the others mean almost the same thing.

1. have = either get or possess
3. get = take or purchase
4. take = have the drink to go

In sentence #1, "Can I have something to drink?" the word "have" means to possess or consume. The speaker is asking if they are allowed to possess or consume a drink.

The difference between the four sentences is subtle:

1. "Can I have something to drink?" - This asks if the speaker is allowed to possess or consume a drink.
2. "Can I drink something to drink?" - This sentence is a bit redundant as it repeats the word "drink." It is asking if the speaker is allowed to consume a drink.
3. "Can I get something to drink?" - This asks if the speaker is allowed to obtain or receive a drink.
4. "Can I take something to drink?" - This asks if the speaker is allowed to physically take a drink with them.

Overall, all four sentences convey the same basic meaning of asking if the speaker is allowed to have or consume a drink, but they use slightly different phrasings.
