tutkimuksensa

Tutkimuksensa is a Finnish noun phrase meaning “their/their own research” or, more broadly, “the research of someone.” It is the third‑person possessive form of the noun tutkimus, which means research or study. In Finnish, possessive suffixes attach directly to the noun, so forms such as tutkimukseni (my research), tutkimuksesi (your research), tutkimuksensa (his/her/its research or their research), and tutkimuksemme (our research) are common. The exact interpretation of tutkimuksensa (singular or plural possessor) is determined by the surrounding context and pronoun.

The form is widely used in formal and academic Finnish. It often appears in phrases that refer to the basis or results of another’s work, for example: tutkimuksensa mukaan (according to his/her/its research) and tutkimuksensa perusteella (based on his/her/its research). These constructions help attribute findings, methods, or conclusions to a specific author or group without repeating a name.

Etymology and relation to related terms: tutkimus is a core noun meaning research or study and is derived from the verb tutkita, “to investigate.” Related terms include tutkija (researcher), tutkimuslaitos (research institution), and tutkimuskirjallisuus (research literature). The possessive form tutkuksensa, tutkimuksensa, or similar variants follows Finnish’s regular pattern of personal suffixes, adjusted for vowel harmony, and is a standard feature of scholarly prose.

In summary, tutkimuksensa is a canonical Finnish possessive construction used to refer to someone’s research, most often in academic and analytical writing, with the exact possessor clarified by the surrounding context.
