Questions & Answers about Işıklar açık kaldığı için akü muhtemelen bitmiştir.
Why is -tir added to bitmiş? Doesn't bitmiş already mean it happened in the past?
Yes, -miş is the past tense, but adding the -tir suffix here expresses an assumption or strong probability. In this lesson's context, attaching -dir or -tir to a verb tells us the speaker is making a logical guess based on the lights being left on. So bitmiştir translates to 'must have died' or 'has probably died'.
If bitmiştir already expresses probability, why do we also need the word muhtemelen (probably)?
It is very common in Turkish to use an adverb like muhtemelen (probably) or belki (maybe) alongside the -dir suffix for emphasis. They work together to reinforce that this is a deduction rather than a confirmed fact.
How exactly does kaldığı için translate to 'because they stayed'?
To say 'because an action happened', Turkish uses the structure: Verb + -dık suffix + possessive ending + için. Here, kalmak (to stay) takes -dık, followed by the third-person possessive -ı (which softens the k to ğ, making kaldığı). Literally, it translates to 'for the reason of its staying'.
