sisendina
Sisendina is an Estonian term meaning “as input” or “in the role of input.” It is formed from the noun sisend, meaning input, plus the suffix -na, which conveys the idea of function or role. The expression is common in technical and scientific writing, where it is used to indicate that something is being used as input for a process, a model, an experiment, or a computation.
Examples of its use include: Need andmed on sisendina mudelile. Andmed esitati sisendina eksperimentaalse uuringu jaoks.
Grammatical notes: The -na suffix yields a noun phrase that expresses a role, often translated as “as”
