The French verb "soupirer" means "to sigh" in English. It describes the act of taking a deep breath or exhaling audibly, usually as an expression of emotion such as relief, frustration, sadness, tiredness, or longing.

Meaning and usage:

Soupirer expresses a non-verbal reaction often tied to feelings or mood.
Example: Il a soupiré de soulagement. ("He sighed with relief.")
It is an intransitive verb (does not take a direct object).

Synonyms and differences:

Respirer profondément (to breathe deeply): This focuses on the act of taking a deep breath more generally without the emotional connotation.
Gémir (to moan, groan): This expresses emotional pain or sorrow but produces a sound different from a sigh (longer, more vocalized).
Pousser un soupir (to let out a sigh): A phrase synonymous with soupirer, sometimes slightly more formal or descriptive.

In short, soupirer specifically means the act of sighing, usually connected to an emotional or physical state.
