English/Parts of Speech/Verbs/Moods/Imperative Mood
Appearance
The imperative mood
has sometimes an exclamation mark (!)
has two forms:
A) an order, a suggestion, a request, a warning to an individuum or group of which the speaker/writer is
not a member!:
Learn these words! Fight for your rights!
it has the form of the infinitive of the verb (without to)
negation with "don't"/"do not"
Don't underestimate the power of intuition. Do not drink and drive.
it can be made more emphatic, if we put "do" in front of the imperative form:
Do wash your hands now. Do stop making a nuisance of yourself.
B) an order, a suggestion, a request, a warning, a summons to a group of which the speaker/writer is
a member: Let's find an answer. Let us concentrate on these statistics.
negation: "Let's not", "Don't let's"
Let's not forget this important fact. Don't let's be too inquisitive now. it can be made more emphatic, if we put "do" in front of the imperative form:
Do let's keep our nerves.
the question tag for sentences with "Let's" is "shall we"?
"Let's phone granny, shall we?"
