The use of the word, wait ? (English)?

Question

Q1 I have been waiting 20 minutes. or I have been waiting for
20 minutes . Which one is correct ?

Q2 I have been waiting for you for 20 minutes. Is this sentence
correct ?

Q3 about the phrase " wait for me" . Can I say it when I am busy helping someone else in the classroom and the students raise their hands, waiting for my help ? or Should I just say," hold on" or "one at a time" ?

Answer 1

In Q1 I think they are both correct but I would choose the second one as less amboguous.
In Q2 that sentence is correct but its tone sounds kind of scolding.
In Q3 wait for me is a bad choice. You could say "I will help you when I am done helping this other student. Please wait your turn."

Answer 2

Q1: i have been waiting for 20 minutes

Q2: yes

Q3: say hold on

Answer 3

As an ex-technical writer..

Q1: "I have been waiting for 20 minutes" is correct.

Q2: Yes.

Q3: "Wait for me." is grammatically correct but may sound a little blunt as a teaching authority. Adding a 'please' may soften the tone. "Hold on" and "One at a time" would also be acceptable but the "please" rule still applies. You can also simply say "Please wait."

Answer 4

Q1 The second shows better usage, but the first is also used in everyday speech.

Q2 Correct.

Q3 Say, " I'll help you in a moment", or "just a moment, please".

Answer 5

All these options actually sound just fine.

Isn't English just a difficult language to deal with? Silly language anyhow!

Answer 6

1. I have been waiting for 20 minutes.
2. Correct.
3. I would use "hold on, please" or "one at a time" it comes off more respectfully. Or even "please wait".

Answer 7

Both

No

I prefer Hold on!
