9vuotista

9vuotista is a nonstandard orthographic variant of the Finnish compound adjective 9-vuotias, meaning "nine-year-old." The variant arises when the hyphen is dropped, a tendency sometimes seen in informal writing, headlines, and certain design contexts.

In standard Finnish, the corresponding forms are created with the hyphen: 9-vuotias for "nine-year-old" (nominative singular) and 9-vuotiaita or 9-vuotiaista for other cases and numbers. The form 9vuotista would be interpreted as the partitive singular of the same concept when hyphens are omitted, but such usage is nonstandard.

Usage notes: 9vuotista is generally understood among Finnish readers but is not recommended for formal writing. It is occasionally encountered in social media, advertisements, and informal communication, where hyphenation or spacing may be reduced for visual or stylistic reasons.
