Questions & Answers about Odkąd schudła, biega dwa razy w tygodniu.
Why does this sentence mix the past tense schudła with the present tense biega?
This is a very common pattern with odkąd (since). The action of losing weight is a completed event in the past, so we use the past perfective verb schudła. However, her habit of running is still ongoing today, so the main clause uses the present tense biega.
Could I use the imperfective past tense chudła after odkąd instead?
You could, but it would change the meaning. Odkąd schudła means 'Since she finished losing weight.' If you used the imperfective odkąd chudła, it would mean 'Ever since she was in the process of losing weight,' which sounds a bit less natural for this specific context.
Why is the translation 'a week' written as w tygodniu?
To express how often something happens during a given period, Polish uses the preposition w (in) followed by the Locative case. The word tydzień (week) changes to tygodniu in this case. So, w tygodniu literally translates to 'in the week'.
Why is it dwa razy instead of dwa raz?
