undersöktes

Undersöktes is a Swedish verb form meaning "was examined" or "was investigated." It is the simple past tense in the passive voice of the verb undersöka, which means to examine, inspect, or investigate. It is used when the subject of a sentence undergoes examination or inquiry without naming the agent performing it.

In Swedish, the past passive can be formed with undersöktes, though in everyday language the more general passive construction became undersökt or the phrase blev undersökt is also common. Examples: "Patienten undersöktes av läkaren." (The patient was examined by the doctor.) "Fallet undersöktes av polisen." (The case was investigated by the police.) The active past tense is undersökte, as in "Läkaren undersökte patienten." The past participle used in perfect tenses is undersökt, as in "har undersökt" (have examined).

The form undersöktes is typical in formal, scientific, medical, and journalistic writing, particularly when the emphasis is on the action itself rather than the agent. It can appear in historical records, case notes, and reports where the performing party is unknown or deliberately omitted.

Etymology: undersöka is a compound of under- meaning thorough or exhaustive and söka meaning to seek. The sense is to seek out or examine thoroughly. The past passive undersöktes thus conveys that a thorough examination or investigation took place.
