The particle の can be used to turn an adjective or a verb phrase into the (grammatical) equivalent of a noun. This is known as 'nominalization'.

When following a verb, a direct translation is usually not needed. When following an adjective, a translation such as 'the one' usually fits:

あか

赤

いのはいいですよ。
The red one is good.

の would typically be followed by another particle to indicate the role of the (new) noun phrase - as the topic (は), as the subject (が), as the object (を), or as an indirect question (か).

の

がわかりません。
I don't know how to cook.

と

すのが

しかった。
He took delight in talking with friends.

はベルが

るのを

いた。
I heard the bell ring.

どこへ

い

行

ったらよいのかわからない。
I don't know where to go.

In colloquial speech, the particle の is often contracted to ん in certain uses, but in this usage of の it is always properly pronounced.
