Questions & Answers about Muhtemelen evde, çünkü hasta.
Where are the words for "he" and "is" in this sentence?
Turkish often drops the subject pronoun o ("he/she/it") when the context makes it clear. As for "is", in the third-person singular, the "to be" suffix (-dir or -tir) is frequently left out in casual speech. So evde (at home) simply implies "he is at home" and hasta (sick) implies "he is sick".
Is muhtemelen related to the word muhtemel?
Could I add the -dir suffix to make it more formal?
Yes, if you were writing a formal report or a news article, you might write Muhtemelen evdedir, çünkü hastadır. But for spoken Turkish and everyday writing, leaving it off like in this example is much more natural and common.
Why is the reason placed at the end of the sentence?
Çünkü means "because" and is used just like in English to connect two ideas. Unlike typical Turkish grammar where you put the verb at the very end of your thought, using çünkü lets you tack the explanation onto the end of the sentence, exactly matching the English word order.
