How is も being used in "トムのうるさいいびきで一睡もできなかった。"?


The sentence

> トムのうるさいいびきで一睡もできなかった。

apparently translates to

> Tom's loud snoring kept me awake all night.

**Question:** What is the role that the も particle is playing in this sentence
(via "一睡も")? I know it typically means "also", but it doesn't seem to make
sense here?




Here, も isn't being used to mean `also` but rather `(not) at all` or `(not)
even`.

So, the phrase `一睡もできなかった` here is referring to the speaker's inability to get
**even** a small amount of sleep, which is translated to/inferred as being
kept awake all night
