Questions & Answers about Лікар оглянув сухожилля.
Ukrainian does not have articles like the or a/an.
So Лікар оглянув сухожилля can be translated as The doctor examined the tendon or A doctor examined a tendon, depending on context. English has to choose an article; Ukrainian usually does not.
Оглянув is:
- past tense
- masculine singular
- from the verb оглянути
It agrees with the subject, so it tells you the subject is grammatically masculine singular: лікар.
It also shows a completed action: the doctor finished examining it.
Compare:
- оглянув = examined, looked over, finished the examination
- оглядав = was examining / examined in a process-oriented or repeated sense
Лікар is in the nominative case, because it is the subject of the sentence: the one doing the action.
In dictionary form, the word is also лікар, so here it appears unchanged.
