4.39 requests, orders, and instructions

When you are making a request, you usually use a 'yes/no'-question beginning with one of the modals 'could', 'can', or 'would'.

• Could I ask you a few questions?
• Can I have my hat back, please?
• Would you mind having a word with my husband?

You can also give an order or instruction using a 'yes/no'-question beginning with a modal.

• Will you tell Watson I shall be in a little late?
