How undersöka conjugates
Group 2b works like 2a, but the past takes -te because the stem ends in a voiceless consonant (k, p, s, t, x): köpa → köper, köpte, köpt. So undersöka → undersöker, undersökte, undersökt.
Passive (s-form)
Swedish makes the passive by adding -s: the doer drops out and the thing acted on becomes the subject. Spoken Swedish often prefers bli + past participle (blev undersök).
| Form | Swedish |
|---|---|
| Infinitive | att undersökas |
| Present | undersöks |
| Past | undersöktes |
| Supine | har undersökts |
