Depends on the context (this is a problem when translating from English to real languages).

Help (noun) - Aide (feminine) or Secours (f)

(I) help - Aide

(You singular) help - Aides

(We) help - Aidons

(You plural) help - Aidez

Note: Unlike Spanish, you need the appropriate pronoun when these are in a sentence.

Gavier covers Help as an imperative/interjection in French.

Au secours!

M'aidez!

Aidez is help.

wow. who ever gave me the 30 lingots, thank you very much. :-)

I like your profile pic! You already know the answer by now :)

[Aide] is help in french and you are doing a good discussion on translation.
