In a very similar way to のは
is used in Japanese for nominalization (creating a noun-like phrase). However, unlike のは
, which is a combination of two particles, こと
is a noun
. To use こと

You should not do things that will cause annoyance to your neighbors. (That which is 'causing a problem in the neighborhood')
I dislike things like faxing. (That which is 'faxing')
It is important to not use too much money. (That which is 'not using too much money')
As we can see from these examples, ない can also be used between the verb and こと
, to form a 'not' statement. There are other auxiliary verbs
that may be used with こと
in this way, but ない is the most common.
Although this lesson discusses こと
pairing with the dictionary form of verbs, it can actually pair with any standard verb form. Standard form just means anything that does not finish with the polite ます.
Unlike もの (another noun used to describe 'things'), こと is a noun that is frequently used to describe things that are 'intrinsic'. This basically means things that are describable, but not necessarily always observable (feelings, conditions, events, etc.).
When a sentence (usually short) finishes with こと
, it quite often has the nuance of being a rule, or command. This こと
is not actually a noun, but a sentence ending particle
as a particle will almost never be written in the kanji form. However, it does originate from the same word.
