So my tutor and I have been talking about this example and I still can't ascertain an answer I understand from him as to why it works (the piece in bold).

ただ走るのではなくて サーかを しながら走るのがいいです

What I understand is that the の acts as a noun connecting piece, just as こと would. What I don't understand is how he has connected 走る with ではなくて. Is this the latter a noun? I really don't understand its use here. Why not say 走っていないけど?

  • What's 「サーか」? Typo?

  • I'm guessing you meant サッカー rather than サーか? Regarding your main question, do you understand the concept of nominalisation? Commented Feb 1, 2021 at 20:46
  • user3856... thank you for that. Yes, nominalisation uses words that aren't nouns as nouns or leading noun phrases... correct? For example, 読むのが好き - to read is no longer a verb with the use of のが.

  • See also this answer to the "What are the grammatical roles of the two のs in the following sentence?" question, particularly with regard to the second の in the question -- this is the so-called "explantory の", which is indeed also a nominalizer as mentioned by @user3856370.

    @user3856370, I haven't thought of it that way either! 😄 My comment was about the second の in that post -- the one at the end in のです. But now that I'm thinking about it, contrasting ~するがいい and ~するのがいい, I wonder if there may be explanatory nuances here too? Something to mull over. Commented Feb 1, 2021 at 21:50

So, from your comment it seems like you more or less understand nominalisation. Let's work backwards from the translation.

ただ走るのではなくて... means "rather than just running ...".

走る is the verb meaning "to run". We need to turn this into "running". To do this we nominalise it by adding の. If your uncomfortable with thinking of "running" as a noun then think of 走るの as meaning "the act of running". That's definitely a noun phrase.

Next we have noun+ではなくて... this literally means "not noun and ...", but that's a useless translation in this context. Quite often ではなくて translates more naturally as "rather than" and that's exactly what it does here.

Finally, your alternative 走っていないけど... would mean "I don't run but ..." which has a rather different feel to it.


The in「ただ走るのではない」is a normalizer. In other words, の turns this verb-phrase 「ただ走る」into a noun. To help you to understand「ただ走るのではない」, it translates to "just-run-thing not" or "it is not only run-thing."
