Meaning
To dissolve or fade away completely, as though nothing had ever been there, with a suggestion of gradual, effortless disappearance. Slightly more poetic and less common than the everyday 'vanished into thin air', it tends to appear in literary or elevated descriptions of mists, moods, crowds, and hopes that dissipate entirely. Literary, slightly poetic register; sounds consciously Shakespearean and is markedly rarer than the 'vanished' version. Regional use: General English (Shakespearean origin).
Origin
This is the closest of the thin-air idioms to Shakespeare's actual wording. In The Tempest, Act 4 Scene 1 (c. 1611), Prospero abruptly ends his wedding masque and meditates on impermanence: 'These our actors, as I foretold you, were all spirits and are melted into air, into thin air', part of the famous 'baseless fabric of this vision' speech. Everyday speech dropped the first 'into air', yielding 'melted into thin air' as a poetic variant, though NoSweatShakespeare notes that 'vanished' and 'disappeared' versions are now the common forms - The Phrase Finder first finds the fused 'vanish into thin air' in an April 1822 Edinburgh Advertiser article. Verdict: genuinely Shakespearean wording, but a minor literary strand of the wider modern idiom.
