Learn Turkish: Yeni arabayı çok beğendik. - We liked the new car a lot.

You are thinking of the present continuous tense (like biliyor-uz, 'we know'). The past tense uses a completely different set of personal endings! In the past tense, the suffix for 'we' is just -k. So we take the root beğen (to like), add the past tense -di, and attach -k to get beğendik (we liked).

Why is it arabayı instead of just araba?

Araba (car) is the direct object of the verb—it is the specific thing we liked. Because it is a specific, known car ('the' new car), it needs the accusative case ending. Since araba ends in a vowel, we add the buffer letter -y- followed by the vowel -ı (matching the 'a' in araba via vowel harmony), giving us arabayı.

When do I use beğenmek (to like) instead of sevmek (to love/like)?

Beğenmek is used when you like how something looks, tastes, or functions—it is about your taste, approval, or a positive first impression. You use it for a new car, a movie, or a good meal. Sevmek implies a deeper emotional attachment, like loving a person, a pet, or a lifelong hobby.

In English we put 'a lot' at the end of the sentence. Why is çok in the middle here?
