[" أبو عبود"]

[QUOTE=ath111;1054833712]

You are right concerning what you have mentioned but for the last point,you are not

The imperative is not a tense but a mood and we use the stem form of the verb without a subject

[/Q
excuse me, you wrote "advices" remember this noun has no plural. never add the "s" to these words:
- advice
-chocolate
- information
-furniture
and many others
advice is singular and it has the meaning of plural, if you want to translate your ideas into English
- a piece of advice =نصيحة
advice =نصائح
remember advice is singular in grammar
example:
here is my advice not " here are my advice"
