What's the difference between "you must stay..." and "you should stay..."? I typed "should" and got counted wrong. Still having problems with "should" and "must". Merci.
"should" is in conditional mood and would back translate to "tu devrais/vous devriez".
Translations need to keep the verb's mood/tense whenever it is possible.
There is no hidden meaning here; it means exactly what it says.
When would it be used? Perhaps you would hear it during circle time for preschoolers when they gather for their daily rituals. Or perhaps for a game.
