To expire or come to an end; to breathe out or exhale.
From Latin expiratus, past participle of expirare (ex- out + spirare to breathe). This is a less common variant or archaic form of the modern verb 'expire,' maintaining the original sense of 'breathing out.'
The original Latin meaning of 'expirare' is literally 'to breathe out'—when someone 'expirates' (dies), they breathe their last breath, which is why so many death-related words connect to breathing and air.
