How to differentiate the receiver of favor(giving) and the receiver of verb?


> アリスが先生に田中にあれを見せてくれる

Let's assume this is in the third person point of view (I'm not included). Now
how do I know, between Tanaka and The teacher, is the one that will be the
target of the verb and the receiver of the favor?

Alice gives the favor of showing that to Tanaka for the teacher.(For teacher's
sake)

Alice gives the favor of showing that to the Teacher for Tanaka.(For Tanaka's
sake)

The scenario is that "Alice shows _that_ to Tanaka, giving/doing a favor to
the teacher."




Your sentence:

> 「アリスが先生{せんせい}に田中{たなか}にあれを見{み}せてくれる。」

has a problem in the 「先生に田中に」 part that is preventing the sentence from making
perfect sense. Depending on your intended meaning, the 「くれる」 part would also
need to be corrected.

If you wanted to say that Alice will show Tanaka something, which in turn will
also benefit the teacher in some way, you could say:

> 「先生のために、アリスが田中にあれを（見せる or 見せて **あげる** ）。」 or
>
> 「アリスが、先生のために田中にあれを（見せる or 見せて **あげる** ）。」

Still, my sentences sound only 90% natural on the native level since they are
based off of your original sentence. To make them sound completely natural,
more information might be needed on exactly how this will benefit the teacher
and/or what it is that Alice is showing Tanaka -- in other words, the whole
story. It might even take two sentences to do it.
