もらう and もらって when used with various forms of verbs


What happens when I post-fix a って to もらう. Example:  
手伝ってもらって.

I know 手伝ってもらう means I receive the favor of someone helping me. But what does
conjugating もらう to its て form does?

Also, in its causative form,  
手伝わせてもらう - A made B help me (as a favor for me)

If I am to conjugate this to 手伝ってもらって, what does it mean?

And finally, its passive form:  
手伝われてもらう - Same meaning as 手伝ってもらう possibly?

Again, conjugating this to 手伝われてもらって, what does this mean?




もらう means the subject receives a favor/thing from someone else. The subject is
typically "I", but it doesn't have to be so. As always, the implied subject
depends on the context.

> 私は手伝ってもらった。  
>  I got help (from someone).
>
> 彼は手伝ってもらった。  
>  He got help (from someone).
>
> 手伝ってもらった。  
>  {Someone} got help (from someone).  
>  (This "someone" is typically "I", but it can be anyone depending on the
> context.)

The te-form can form a request, as you probably know. Therefore:

> 手伝ってもらって。  
>  (You should) Get help (from someone).  
>  Let {him/her/someone} help you.

`させて + もらう` is not so uncommon. Here, the "favor" itself is a causative
expression. Note that させる can also describe allowance:

> 私は手伝ってもらった。  
>  I received a favor of helping (me).  
>  I got help (from someone).
>
> 私は手伝わせてもらった。  
>  I received a favor of letting me help (someone).  
>  Thankfully, I was allowed to help (someone).

`られて + もらう` is a very rare combination and you may want to forget it for now.
In case you're curious, it's possible to say something like this:

> 私は彼に怒られてもらった。  
>  I received his favor of being scolded (by someone else).  
>  I got him to be scolded (e.g., on behalf of me).  
>  (It's far more natural to say 彼は(私の代わりに)怒られてくれた.)
