Questions & Answers about Kuzenim evde yalnızdı, ona uğramam lazımdı.
How exactly does uğramam lazımdı translate to 'I had to stop by'?
This uses the past necessity structure you are learning. First, we take the verb stem uğra (to stop by), add the short verbal noun ending -ma, and attach the 'my' possessive suffix -m to get uğramam (my stopping by). Then, we add lazımdı (it was necessary). Literally, the phrase means 'My stopping by was necessary.'
Why is it ona uğramam instead of onu uğramam?
The verb uğramak (to stop by / to drop in) requires the dative case (the 'to' or 'towards' suffix) in Turkish, not the direct object (accusative) case. You are dropping by to the person. Therefore, the pronoun o (he/she) takes the dative suffix to become ona (to him/her).
Could I use gerekiyordu instead of lazımdı in this sentence?
Yes! You could absolutely say ona uğramam gerekiyordu. Both lazımdı and gerekiyordu mean 'was necessary' and are completely interchangeable when talking about personal necessity in the past.
How does yalnızdı mean 'was alone'? Is -dı a past tense marker for verbs?
