May I go to toilet,please? May I go to the toilet,please?

May I go to the toilet, please? 係正確既

點解?

因為响 "go to the + 地方名詞" 入面既 the 係用來指明你去邊一個。
例如你呢句 May I go to the toilet, please? 係想間接地指明最接近果個。

而幾時唔用 the 即係 "go to + 地方名詞"。
例如 ：
I go to school. ( 我上學去。)
I am going to heaven. (我會上天堂。)
He is going to hell. (他會下地獄。)

英文唔用 the 當要去既地方只有一個或者係唔需要指明既。
好似 ( 我上學去) 呢度既學校係說話人每日去果間。
而天堂同埋地獄基本上只有各一個，當然有人會話天堂同埋地獄有好多個。
不過呢點同文法 the 無關。

希望可以幫到你=）......................................

Both are correct.

Reasons:

"May I go to toilet, please?"

=> when the sentence has lefted out the word "the", it means you are making a request to go to toilet, in general. Grammatically it is correct when you refer to your action/wish in going to toilet or loo (loo is a slang for toilet).

"May I go to the toilet, please?"

=> Normally when you added the word "the", it explicitly pointed out to "the toilet". In this sense, you are referring to a specific toilet in your mind and you wish to go to the place instead of the action.



Hope this helps.

May I go to the toilet, please? is correct.

the first one is right, because you need a preposition before a subject

well sometimes people dont say it that bluntly, you can say "May i use the restroom" instead, but either one is fine
