Read the Mathematica tutorial on Contexts.
Here's one paragraph therefrom:

The basic idea is that the full name of any symbol is broken into two
parts: a context and a short name. The full name is written as
context`short, where the ` is the backquote or grave accent character
(ASCII decimal code 96), called a "context mark" in Mathematica.

 Is it the same symbol as it is used for NumberMarks i.e. 0.3333333333333333` for example?
