In plain English: Nothing is the complete absence of anything at all.

Usage: Use nothing to refer to a trivial matter or something insignificant that does not warrant attention. Avoid confusing it with the concept of non-existence when you simply mean an unimportant detail.
Not at all; in no way.

In plain English: Nothing means not at all or to no degree when used as an adverb.
"I tried to fix the radio, but nothing worked."
Usage: Use nothing as an adverb to emphasize that something happens to zero degree or in no way, typically modifying verbs or adjectives like "nothing matters" or "I can't do nothing better." Avoid using it as a noun unless you are specifically referring to the absence of anything.
Not any thing; no thing.
"After searching through every drawer, I finally realized there was nothing left to eat in the kitchen."
The word "nothing" comes from Middle English nothyng, which was formed by combining the negative "no" with "thing." It originally meant "not any thing," reflecting a literal construction that has remained consistent in its core meaning over time.
