How do adverbs change when changing くれる to もらう?

Question

Consider the following part of a sentence:

親切に教えてくれた。

Here, the subject of the sentence is the person who is the "giver". Furthermore, "親切に" is like an adverb for 教えてくれた. In English, a potential translation is "she kindly taught me".

Now consider this alternate phrasing:

親切に教えてもらった。

Here, the subject of the sentence is the person who is the "receiver". To show this, we might translate the sentence like "I had her teach me".

The problem is: what does 親切に ("kindly") mean in this case?

As far as English is concerned, there is definitely a difference between

I kindly had her teach me

versus

I had her kindly teach me

... which brings us to another question: In "親切に教えてくれた", is it the teaching that is done kindly, or is it the "giving" that is done kindly?

In conclusion, how are くれる and もらう affected by adverbs, and how do adverbs change when changing a sentence from くれる to もらう?

Answer 1

I will start from the end. くれる and もらう are auxiliary verbs, which modify main verb. Auxiliary verbs never modified by adverbs. So, in both cases it is "kindly taught".

Also, adverbs is not always sound natural in English if translated literally, that doesn't mean they changed somehow in Japanese.

Second sentence may be translated as

I was kindly taught.
