Role of をする in 学習の助けをするおもちゃ


I am triing to figure out the use of をする in 学習の助けをするおもちゃ translated as _toys
to help you learn_ in [this
article](https://newsinslowjapanese.com/2020/10/16/nisj-362-can-you-solve-
this-problem/)

I learned a bit about noun + する / をする in [this
post](https://japanese.stackexchange.com/questions/4006/difference-
between-%e3%81%b9%e3%82%93%e3%81%8d%e3%82%87%e3%81%86-%e3%81%99%e3%82%8b-and-%e3%81%b9%e3%82%93%e3%81%8d%e3%82%87%e3%81%86%e3%82%92-%e3%81%99%e3%82%8b)
but for what i understand so far we use 助ける which is a verb not a noun.
Furthermore from my beginner point of view 学習の助け would already mean "help to
learn" all by itself isn't it?




I must first point that Japanese text in the article you cited has a few not
fully natural places, including the very phrase 学習の助けをするおもちゃ you asked. I
don't know if it is because the writer tries to reduce grammar level or due to
their fluency.

学習の助け is a common expression to mean "learning aid" or "aid to learning", and
[助け](https://dictionary.goo.ne.jp/word/%E5%8A%A9%E3%81%91/) is a noun "aid,
assist, helping hand" as you said. If you want to literally translate _toys to
help you learn_ , you have several options:

  * 学習を助けるおもちゃ "toys that (will) help learning"
  * 学習を助けるためのおもちゃ "toys for helping learning"
  * 学習の助けとなるおもちゃ "toys to be aids to learning"
  * 学習の助けのためのおもちゃ "toys (made) for aids to learning"

However, the collocation 学習の助け **をする** おもちゃ (which would be "toys work as aids
to learning") is extremely rare*, especially for inanimate objects which are
not self-aware to do something. 助け can certainly connect to ～をする much more
often as a base of compounds: 手助けをする, 人助けをする..., but I'd rather recommend
remembering **～の助けとなる** as a set phrase for your meaning.

Note that there is no る after 助け. 助ける is a verb ("to help", "to support"), but
助け without る **is a noun** ("a help", "an aid", "a support"). It's an example
of [masu-stem as a noun](https://japanese.stackexchange.com/a/32311/5010).
学習の助け is a noun phrase made by joining two nouns using の ("a learning
aid/support"). That's why you can attach をする to it.

You can rephrase this to 学習 **を** 助け **る** おもちゃ. Now 助ける is used as a
transitive verb, and there is を instead of の. Your second link has an
explanation. See also: [Jlpt/n5q5: 弟は部屋◯掃除をしました。◯: の versus に
