käsikirjassa

käsikirjassa is a Finnish word that translates to "in the handbook" or "in the manual". It is a grammatical form, specifically the inessive case of the word käsikirja. Käsikirja itself means handbook, manual, or script. The inessive case indicates a location or state of being within something. Therefore, when someone refers to something being "käsikirjassa", they mean it is contained within, described in, or part of a handbook or manual. This could be a specific instruction, a piece of information, or a reference. The word is commonly used in contexts where procedural documents, guidelines, or instructional texts are relevant, such as in technical fields, educational settings, or when discussing rules and regulations. It signifies that the information being discussed is officially documented and can be found within a designated reference source.
