Aurélie Drouard · Accepted Answer

Bonjour Yellamaraju !

The word "pis" is the old version of "pire", and as such it is used much less in speech and written French nowadays.
You will usually encounter "pis" in fixed expressions, such as "de mal en pis" (you would never say "de mal en pire") or "tant pis" (i.e. too bad).
The rest of the time, you use "pire" to express "worse"

I hope that's helpful !
A bientôt !

Ma mémoire est de pire en pireMy memory is getting worse and worse
This seems to be different to some of the other sentences since they use verbs like "aller" and "devenir" - there's nothing here that seems to be translate as "getting worse"
