How is "誰も" used in this sentence?


I am a bit confused about a sentence I came across in an anki deck:

誰もその話を知らない。

I know that that 誰 means "who" and も means "also", but the translation it
gives me is:

"No one knows that story."

Someone please explain.

Thank you n_n




`誰` by itself does not mean 'who'. Nor does `も` always mean 'also'. Words like
`誰` are called indeterminates, and are more essential than wh-words (It can be
a part of the meaning of a wh-word; Not wh-word itself). `誰` only means 'some
variable (something that does not have a fixed reference) that ranges over
people'. Depending on what particle it is used with, it would be translated
into different words in English:

> 誰 who  
>  誰か someone  
>  誰も anyone/everyone
