So, from my search it seems a lot of people say that there are almost no
differences between による and によっては. Nevertheless, my grammar books says that
によっては can be used like for "on the possibility of something happen". An
example:

> 国によっては安楽死が認められている。

So this sentence, instead of translating like "Depending on the countries,
euthanasia may be allowed", a more proper translation should be "Depending on
the countries, there is a possibility that euthanasia may be allowed".

Whoever it also adds, that there are some exceptions, and 晴れ時々曇り、所により雨 also
has a nuance of possibility that something will happen.

Can someone please add some more example sentences to explain this? It seems
that による has just so many uses, and I´m getting quite confused distinguishing
between them all. Thank you.

grammar nuances
による for highlighting differences
First of all, I do not necessarily think that 「～～による」 has so many usages at
all. It certainly is a very useful phrase and therefore, it is used
frequently, but it has a rather limited meaning and usage -- " _ **to depend
on ~~**_ ".

I naturally have no idea exactly what your grammar book says, but as a
Japanese-speaker, I do know for sure that the sentence:

> 「[国]{くに}によっては[安楽死]{あんらくし}が[認]{みと}められている。」

does _**not**_ mean either

> "Depending on the countries, euthanasia _**may**_ be allowed" or
>
> "Depending on the countries, _**there is a possibility**_ that euthanasia
> _**may**_ be allowed."

From where in the original Japanese sentence are you getting " _ **may**_ " or
" _ **possibility**_ "?

That original sentence simply means:

> "Depending on the countries, euthanasia is allowed."

Regarding the often-used expression in weather forecast:

> 「[晴]{は}れ[時々曇]{ときどきくも}り、[所]{ところ}により[雨]{あめ}」

It does not explicitly say "possibility that something will happen". It is
just that weather forecast is all about possibilities in the first place. That
phrase just means:

> "Sunny, partly cloudy with isolated showers."

It is true, though, that 「～～による」 and 「～～によって」 appear at different places in
sentences, and that may be part of your confusion.

For instnace, the sentence above about euthanasia can be rephrased as:

> 「安楽死が認められているかどうかは、国による/よります。」 or
>
> 「安楽死が認められているかどうかは、国によって[異]{こと}なります。」

Both mean the same thing as the original.
