This is the 925th most frequent Estonian word.
sind
"You" (singular, accusative case).
Here, 'sind' is the accusative form of 'you', used to indicate the direct object of the verb (whom I saw).
Ma nägin sind eile parkis.
I saw you in the park yesterday.
'Sind' here emphasizes the individual being directly addressed or talked about as the receiver of the praise, aligning with the direct object usage.
Kas õpetaja kiitis sind tehtud töö eest?
Did the teacher praise you for the work done?
Although 'sinust' appears here, it provides context on related usage. 'Sind' would translate to 'you' as the direct object in similar sentences, indicating the addressed person.
