yhteystietoihinsa

Yhteystietoihinsa is a Finnish morphological form built from the noun yhteystieto, meaning contact information. The form combines the illative plural suffix -ihin, indicating direction toward or into something, with the third-person possessive suffix -insa. The resulting word can be understood as “to his/her/its contact information” (or into that contact information) depending on the grammatical context.

Morphology and construction: In Finnish, several suffixes can attach in a chain to a base word. For yhteystietoihinsa, the base is yhteystieto (singular). The illative plural suffix -ihin attaches to form yhteystietoihin (into the contact details). The possessive suffix -insa is then added to indicate ownership by a third person. The combination yields a word where the meaning blends direction toward someone’s contact details with possession by that person, producing a form that is commonly translated as “to his/her contact details.”

Usage and context: The form is primarily found in written Finnish and in more formal or technical contexts, such as documentation, manuals, or formal correspondence, where one needs to specify direction toward or targeting of a person’s contact information. In everyday language, speakers more often use simpler constructions such as yhteystietonsa (his/her contact details) or adjust the case to reflect the sentence’s function.

Examples and alternatives: A sentence illustrating the idea could be interpreted as “Lähetä viesti yhteystietoihinsa,” meaning roughly “send a message to his/her contact information.” More common variants include yhteystietonsa (his/her contact details) or yhteystietoihinsa in contexts that require explicit illative/directional meaning.
