Nothing vs. No Thing
In this part we will discuss the different spelling of nothing with and without space between the two parts and we'll see which one is correct and more useful.
Which One Is Standard?
If you want to use 'nothing' as an indefinite pronoun, always write it as one single word.
'No thing' is not a pronoun, but a noun phrase. Let's take a closer look at each one:
When we put 'no' and 'thing' as a two-word noun phrase, i.e. 'no thing', note that the 'thing' must be a concrete thing (a thing that can be seen or touched), so when we say 'no thing', it means there is a presence there, but it has no touchable form.
I thought I saw something there, but it was
Another use of the noun phrase 'no thing' is when we want to put another word between the two, for example:
'Nothing' is an indefinite pronoun. It means 'not anything'. It shows the lack of a single thing.
Don't Use Negative Verbs with 'Nothing'
Always keep in mind that we do NOT use negative verbs with the pronoun 'nothing'. Because 'nothing' is a negative marker by itself.
This is a case of 'double negation' which is not grammatically correct.
