Start of line “^”, then an “n”, then any word characters zero or more times (\w*), then a “g”, then the end of the line “$”. The surrounding slashes are convention for certain regex languages, and the last “i” turns on the case insensitive flag.
Personally I’d write this as “(?i)\bn[a-z]*g\b” but there’s many approaches for many different situations.
Because i struggled to understand what you meant I'd like to rephrase it:
It matches only if the regex is applied to a singular word. It's not going to match if there is a sentence or any apostrophe etc, which is implied to be valid input because it supposedly matches "all words".

That regex doesn't do what the description above it says, with or without a backslash.
How so?

I assume mostly using start of line instead of \b, and expecting w only to be zero+ times in the middle.

That’s easy to misunderstand. And if humans have trouble with it, then I won’t blame the poor AI.
Getting an AI to ask clarifying questions would be useful, of course…
I guess it doesn't work for example when words contain dashe(s) or apostrophe(s) which might exist (for a single indivisible word) in some languages.
