What does "Util" mean in modules?

I’ve been exploring Roblox’s chat modules, trying to find something useful. When doing so, I always stumble across a module that’s always named Util. Sorry for not knowing, or being oblivious towards its obviousness, but my perception of it is that it’s responsible for every other module script alongside it? I don’t know. If anyone can answer my question, it would make my day.

TL;DR What does it mean?

Util, short for Utility, usually houses functions that multiple other modulescripts uses


So it’s basically a main module, and any other module is just a function for utility?

Other way around, util just has functions that are common among the modulescripts to perform tasks. But each modulescript can have functions exclusive to itself
