Imposibile

Imposibile is not a standard Italian adjective. In Italian, the correct form is impossibile, meaning not possible or unable to be done. The spelling imposibile with a single s is generally regarded as a misspelling or typographical error, though it may appear occasionally in informal writing or as a stylistic choice in branding or titles.

Etymology and orthography: the word derives from Latin impossibilis, formed from the prefix in- plus possibilis. In Italian, the prefix before p typically yields im-, and the root retains its double s, producing impossibile. The single-s variant imposibile does not reflect standard Italian orthography and is not listed as a correct form in dictionaries.

Usage notes: in formal writing, education materials, and most publications, impossibile is the accepted spelling. If imposibile appears, it is usually an error to be corrected, unless it is quoted verbatim from a source, used intentionally as a stylistic device, or part of a branding name. Comparatively, Spanish uses imposible and English uses impossible, reflecting different orthographic conventions for the same concept.
