undersöker

Undersöker is a Swedish verb meaning to investigate, examine, or study something carefully. It is used in many contexts to indicate a thorough inquiry into facts, conditions, or data, including research, medicine, law enforcement, and journalism. The term emphasizes systematic observation and analysis rather than casual checking.

In medical contexts, doctors undersöker patients by examining symptoms, ordering tests, and reviewing histories to arrive at a diagnosis. In research, scientists undersöker phenomena or hypotheses through experiments and data analysis. In law enforcement and the judiciary, authorities undersöker suspects or circumstances to establish facts. In journalism, reporters undersöker information and sources to verify accuracy.

Grammatically, undersöker is the present tense form used for third-person singular and plural subjects; the infinitive is undersöka. The past tense is undersökte, and the supine is undersökt, used with auxiliary verbs such as har or hade (for example, jag har undersökt).

Etymology and related forms: the verb is formed from söka (to seek) with the prefix under-, conveying thoroughness. Related nouns include undersökning (investigation, examination) and undersökare (investigator). The term is commonly contrasted with synonyms such as granska, utforska, and utreda, which carry nuances related to checking, exploring, or clarifying.
