täyttäjänä
Täyttäjänä is a Finnish grammatical form derived from the verb täyttää, which means to fill, to satisfy, or to complete. The form is the present participle used in the role of an adjective or noun phrase, often translated into English as “as a respondent,” “as a filler,” or “in the capacity of fulfilling.” It functions as a modifier of a noun, describing a person or thing that performs the action of filling or satisfying a requirement. In many contexts, täyttäjänä refers to someone who completes a form, provides an answer, or supplies necessary information, such as a respondent in a survey or an applicant filling out a registration.
The participle is formed by adding –en to the verb stem and then attaching the nominative case
