4.239 giving instructions and making requests

Instead of beginning a question with 'can' or 'could' when you are making a request, you can begin it with 'is' and the impersonal pronoun 'it'. After 'it', you put an expression such as 'all right' and either a 'to'-infinitive clause or an 'if'-clause.

You can use 'want' instead of 'would like' to give an instruction or make a request. 'Want' is more direct and less polite than 'would like'.

'Wanted' is also sometimes used. It is more polite than 'want'.
