How to consider 2 exact cell even if they are different

Question

I try to say at excel that 2 cells are identic even if 1 word change between cell.

For example :

In my cell A1, I have    : money of monday
In my cell A2, I have :    money monday

I did it for all space, character like '' ... but I don't know how to do it for every "parasyte word" like "the of, ...... "

Thanks for reading me !
