soixantecinq

Soixantecinq is a representation of the number sixty-five in French when the two words soixante and cinq are written without a hyphen or space. The standard French form is soixante-cinq, with a hyphen. The concatenated variant soixantecinq is nonstandard and relatively rare, appearing mainly in informal writing, typographic constraints, or as a stylized label in branding or data identifiers.

In French, numbers from sixty to sixty-nine are formed by combining soixante with the numbers one through nine, as in soixante et un (61) and soixante-cinq (65). The usual orthography uses hyphens to join the parts, and there is no formal variant that omits the punctuation in standard written French. When soixantecinq appears, it is typically due to editorial style choices, a system constraint in software or file naming, or intentional branding rather than accepted linguistic usage.

Usage of the unhyphenated form is therefore limited and noncanonical. It may surface in contexts where space, encoding, or typographic rules encourage compact strings, such as domain names, filenames, programming identifiers, or marketing materials. In formal writing, education, and most scholarly works, soixante-cinq remains the preferred representation.
