Learn Turkish: Bu binadaki yükseklikten bende çarpıntı başladı. - I started having palpitations from the height in this building.

You can definitely use yüzünden or için, but the ablative case -DAn is a very common, concise way to express a physical or emotional cause. By attaching -ten, yükseklikten directly translates the concept of getting palpitations 'from' or 'due to' the height.

Why does the Turkish sentence use bende (at/on me) when the English translation says 'I started having'?

In Turkish, medical or physical conditions like çarpıntı (palpitations) or ağrı (pain) are often treated as the subject that 'starts' or 'exists' inside a person. Instead of 'I started the palpitations', the literal structure used here is 'palpitations started in me'.

Is çarpıntı the direct object of the verb başladı?

No, çarpıntı is the subject! Since the literal translation is 'palpitations started', the noun çarpıntı is the thing performing the action. That is why it appears in its bare dictionary form without an accusative object marker.

How does the suffix -ki function in the word binadaki?

The suffix -ki attaches to the locative word binada (in the building) to turn it into an adjective. It directly links the location to the noun that follows it, translating to 'the height [that is] in this building'.
