The term "go flat" has its roots in the verb "go" and the adjective "flat".
The word "go" traces back to Old English "gān", which means "to walk, go, travel, or proceed". It is derived from Proto-Germanic "gāną", ultimately from the Proto-Indo-European root "ghē-", meaning "to leave". The verb "go" has retained its meaning of moving from one place to another.
On the other hand, the word "flat" has a more complex etymology. It comes from the Old Norse word "flatr", which means "level" or "plain". The Old Norse "flatr" is akin to the Old English word "flet", also meaning "flat" or "level".
