When are one-word imperatives used?
When the listener knows clearly what action (verb) he has to do but hesitates to do it, the speaker can use a one-word imperative to urge the listener to do it. Right?
For example, the speaker tells the listener to dig a hole, "Can you dig a hole?", but the listener does not do it right away. In this case, the speaker can use the one-word imperative "Dig!" to urge the listener to dig a hole.
For example, you and your child go to a church to pray, but when you pray, your child does not do it. In this case, you will use the one-word imperative "Pray!" to urge your child to pray.
For example, you tell your child to eat his food, but he still does not eat it. In this case, you will use the one-word imperative "Eat!" to urge your child to perform the action of eating.
Sorry for what I said may not be polite, friendly but I just want to know the correct usage of 1-word imperative sentences. Thank you very much!
