Hello ![:rolleyes:](https://community.mp3tag.de/uploads/default/original/1X/3a79e8b0b7d169b30216785521d7c6f4f895c421.gif ":rolleyes:")  
I' m trying to replace a specifique letter with something else but only if its the last letter of a word  
For example, in a random phrase "Flowers & guns" I'm trying to replace the "s" with lets say "t"  
I've been using ACTION\>REPLACE\>"s "\>"t " (with space) but that covers only the first word.  
If I use wildcard ".s" then all the "s" gets replaced & I dont want that.  
Is there a way to make a rule that replaces only the last letter of a word if it is a specifique one?

That should cover all words with an s at the end, followed by a blank.  
You could try 2 actions of the "Replace with regular expression" as an action group.  
The first handles the words followed by a blank (e.g. with the expression you have already tried).  
The second handles the words at the end of the field:  
Search-String s$  
Replace with: t

Works like a charm. Thank you 🙂
