Questions & Answers about Hastalıktan ötürü evde kaldı.
Why does the word hastalık take the -tan ending here?
The postposition ötürü (meaning "due to" or "because of") always requires the noun before it to be in the ablative case, which is the -DAn suffix. Because hastalık ends in a hard consonant (k), the suffix takes the hard form -tan.
Could I use dolayı instead of ötürü in this sentence?
Yes, hastalıktan dolayı means the exact same thing. Both dolayı and ötürü follow the ablative case and show reason or consequence. Dolayı is slightly more common in everyday speech, while ötürü can sound a bit more formal, but they are fully interchangeable.
Can I express this same idea without using ötürü?
Yes! You can often just use the ablative case on its own to show a reason: Hastalıktan evde kaldı (literally "He stayed at home from illness"). Adding ötürü just makes the cause-and-effect relationship more explicit, much like using "due to" instead of "from" in English.
Why didn't the k at the end of hastalık soften to a ğ?
