Let us consider the sentence
We will study certain lattice, or discrete, particle systems.
Let me explain what I am trying to say here. For my potential reader the expressions "lattice particle systems" and "discrete particle systems" are synonymous, and sometimes they have equivalent meanings. In this sentence I aim to establish a convention that those expressions mean exactly the same thing in the following text. (I would like to have two options because I am going to refer to such particle systems multiple times).
Have I chosen a legitimate way to do so?
