"Please help me!"
Translation:Bonvolu helpi min!
Much as I know, I think It's right Bonvolu helpi min, because as in most languages there can be only one verb in a tense at a time, so here's my explaination
Bon+vol+u is actually a verb in imperative, so this is basically saying "Have a good will to help me".
Oh thanks, that helps! I was wondering where the verb was... That clears it up
I'm very confused too. Could someone explain why its "Bonvolu HELPI min" or "Mi petas HELPU min"?
You can't have two imperatives in the same clause. In the first example "bonvoli" (to be of good will) is imperative so "helpi" needs to be in the infinitive. You could turn "helpi" into an adjective: "bonvole - 'goodwillingly'" and then use "helpu" - "Bonvole helpu min". In the second example "Mi petas" means "I request" and usually goes at the end of the request: "Helpu min, mi petas" - "Help me, I request". "Helpi" is the verb you want the other person to do and so it takes the imperative. In the two example you give, "helpi" is serving two different functions and so takes two different forms.
