käsikirju
Käsikirju is a Finnish noun that appears in some texts as a form referring to a manuscript or written document. It is not a standard modern Finnish term for everyday use; the more common words are käsikirja for a handbook or manual, and käsikirjoitus for a script or screenplay. When käsikirju is encountered today, it is typically interpreted as an older or dialectal variant, or as a shorthand for a hand-written draft or manuscript rather than a finished, printed work.
Etymology and usage context: the word is formed from käsikirja (handbook or manual) with the noun-forming suffix
In contemporary Finnish, the recommended terms are käsikirjoitus for a script (as in film, theater, or broadcasting)
