Questions & Answers about Hãy hít thở.
Hãy is a marker used to make a command, instruction, or encouragement.
So the pattern is roughly:
- hãy + verb
In this sentence:
- hãy = marks an imperative like do..., please..., or go ahead and...
- hít thở = the action
It often sounds a bit more deliberate, instructional, or written than plain everyday speech.
Yes. Hít thở by itself can still work as a command, especially in speech.
Compare:
- Hãy hít thở. = somewhat more formal, instructional, or emphatic
- Hít thở đi. = very natural spoken command, like Breathe / Take a breath
- Hít thở nhé. = softer, gentler suggestion
So hãy is not required, but it changes the tone.
