Here are some of the most common errors using something, someone, anything, anyone, etc. The correct form is given first:
- I didn't bring anything to drink.
- I didn't bring nothing to drink.
- I don't know anybody at the party.
- I don't know nobody at the party.
- There isn't anywhere else to go.
- There isn't nowhere else to go.
The words nothing, nobody, nowhere are already negative; consequently, you do not use these words with "not." The following paired sentences are interchangeable:
- I do not know anybody in my apartment building. I know noboby in my apartment building.
- I don't know anything about it. I know nothing about it.
- Did you understand anything I said.
- Did you understand something I said.
We nearly always use anything, anybody, anywhere when asking questions, but this is not a strict rule.
- There is nobody here.
- There is no body here.
Be careful! These are combination words and you must write them as one word: anything, anybody, anywhere, nothing, nobody, nowhere. If you do not, they have a different meaning.
In the incorrect sentence, the meaning is "There is no (dead) body here."
