What does deflated mean?
'Deflated' serves two closely connected purposes in English. In its literal sense it describes something — a tire, balloon, or cushion — from which air or gas has escaped, leaving it soft, limp, or collapsed. In its far more frequent figurative sense it describes a person's emotional state after a disappointment: someone who is deflated has lost their confidence, excitement, or sense of importance much as a punctured balloon loses its air. A job candidate might feel deflated after a curt rejection email; a speaker's voice may sound deflated when met with silence. The word is standard throughout the English-speaking world, works comfortably in both casual conversation and formal writing, and pairs naturally with verbs such as feel, look, and seem. Its enduring appeal lies in the vividness of the metaphor: disappointment rendered as escaping air, sudden and audible, leaving what was once full noticeably smaller.
Of 'deflate': released air or gas from something, causing it to collapse or shrink; caused someone to lose confidence or enthusiasm.
"A single harsh review deflated her enthusiasm for the project."
Often used figuratively with abstract subjects such as criticism, failure, or news.
Limp or collapsed because air or gas has escaped; showing or characterized by a loss of confidence or spirits.
"She gave a deflated shrug and returned to her desk."
Frequently predicated with feel, look, or seem when describing emotions.
The same word that describes a punctured bicycle tire also perfectly captures the feeling of having your pride quietly let out like air.

Etymology of deflated
'Deflated' is the past participle of 'deflate', formed in the early modern period from the Latin prefix de- ('down, away') combined with 'flare' ('to blow'), the same root that gives us inflate, conflate, and flatulence. The verb entered English around the early 18th century in its literal sense of releasing air, and its figurative use for deflating egos and spirits followed soon after. Cognates sharing the flare root include inflation, flavor-related terms are unrelated, but flat itself traces to the same notion of being blown out or spread flat.

As an emotional descriptor, 'deflated' carries a mild, often sympathetic connotation and is common in both informal speech ('I was so deflated') and journalistic prose. The figurative sense derives transparently from the physical one, via the image of air escaping from something once taut or full.
