muistikirjoissa

Muistikirjoissa is a Finnish noun form meaning “in the notebooks.” It is the inessive plural form of muistikirja, a compound noun meaning notebook or diary. The word is formed from muistikirja, itself a combination of muistio or muisti (memory) and kirja (book). In Finnish, the inessive case marks location, and the plural form of a noun takes the -t ending plus the inessive suffix -ssa or -ssä. For muistikirja, the plural nominative is muistikirjat, and the inessive plural is muistikirjoissa, i.e., “in the notebooks.”

The form is commonly used when referring to contents stored inside multiple notebooks, such as personal journals, planners, or note pads. It can appear in discussions of organizing notes, archival practices, or everyday journaling. For example, Laatikossa on synkronoidut muistiinpanot muistikirjoissa, and often a more natural phrasing is provided by reordering: Muistiinpanot ovat muistikirjoissa. Another example: Hänen muistikirjoissaan on monia ideoita.
