Turning a verb phrase into a noun: dictionary form + の

Japanese has no infinitive and no *-ing* noun. Instead you take a whole plain-form clause and glue の on the end; the result behaves exactly like a noun and takes が, を, は as needed.

ClauseAs a nounWhole sentence
JapaneseEnglish
I like watching films.
Studying Japanese is interesting.
Getting up early is hard.
I forgot to turn off the light.
Did you know he got married?
I'm waiting for him to help.

The clause before の is always plain form. ✕ · ○. A な-adjective or noun takes な: .

の vs こと

Both nominalise. Which one you can use depends on the verb that follows.

Following verbUseExample
perception: の only
の only
こと only
either
either, の is more spoken

Rule of thumb: if the action is right there in front of you — you can see it, hear it, wait for it, help with it — use の. If it is an abstract fact or an ability, use こと.

Cleft sentences: 〜のは … です

Move whatever you want to spotlight to the end and let の carry the rest. The が inside the clause never becomes は.
