In a manner that is coming to an end or fading away, often used to describe a sad, weakening, or dying state.
Expiring + -ly (adverb suffix), derived from the Latin expirare. This rare adverb emphasizes the quality of something weakening toward its conclusion.
This is such a rare and literary word—you'd find it in old novels describing a dying character's 'expiringly soft voice,' giving readers a sense of something beautiful but fading.
