Imperatives come in 3 flavours and personal pronouns.
They all involve action in the present moment only, no past or future concerns.
The suggestion imperative is the plural we [noi].
All other imperatives only use the subject you, singular or plural, polite or personal.
Tu/Voi is used in addressing members of the family, peers, children, close friends, and animals. Otherwise Lei and Loro are used.
The personal pronouns are very important but never used.You need to know which ones you are using.
The three Imperative forms are suggestions, negative imperatives and ordinary imperatives.
These only use the personal pronoun we [Noi] and are equivalent to the English “Let us” or colloquially “Let’s”. They are very easy and useful
Andiamo has two different special meanings.
An Imperative suggestion [and order], let’s go!.
The other meaning is the simple present tense andiamo, we go, or we are going and sometimes loosely we will go. All have a hidden Noi in front of them.
They are completely different meanings.
Let’s try [proviamo} some of the irregulars.
[Noi] diamo, lets give, stiamo, let’s stay, facciamo, let’s do, diciamo, let’s say.
Remember all imperatives other than suggestions are you singular or plural.
For suggestions just use non in front, non diamo lets not give.
But the negative imperative for tu in all conjugations is formed by placing the word non before the infinitive.
Non parlare, don’t speak. Non dicere, don’t say. Non finire, don’t finish. very easy.
for voi use the plural form. Non parlete.
Ordinary imperatives are a little tricky.
