Questions & Answers about Tu devrais réduire tes efforts parce que tu t'essouffles plus que les autres.
Why are plus and que right next to each other in this sentence?
Do I pronounce the 's' at the end of plus here?
Why use devrais instead of dois?
Devrais is the conditional form of devoir. While tu dois means "you must" (a strong obligation), tu devrais translates to "you should". It is used to give advice, which makes the suggestion to reduce effort sound much softer.
