Why is it "bunu" and not "buyu"? -yu is the accusative suffix for words that end with a vowel, -nu is the accusative suffix for words that already are suffixed and end with a vowel. Or am I wrong?
this is an exception and it is only for o bu and şu as far as I know.
How about su?
su or şu? it is valid for O / BU/ ŞU only as I wrote above, not for su (water).
No I meant su as in water is also an exemption right?
No, accusative form of 'su(water)' is 'suyu'.
The same irregularity goes for 'şu' and 'o', too.
you're right! but it's irregularity. in most of the languages pronouns are irregular and they have to be memorized.
you wrong ı am turkısh ! this is not buyu this is bunu !!
Why is it "bunu" not "bu"
It is a specific direct object and requires the accusative case :)
HOW CAN I KNOW THAT IT IS specific direct object
why not '' siz bunu okursiniz '' ???
Vowel harmony! The final vowel in "okur-" is a -u, so the suffix will also contain u's. This explains 4-way vowel harmony using the accusative, but it is still applicable to all other instances of it: https://www.duolingo.com/comment/9041808
I didn't get when I should use bunu. Do we have to use bunu every time we use bu as an object?
Yep :) There are a few verbs that will take a different case though, but the majority of verbs will take the accusative.
what will be translation 'You read these'
Bunları okursun(singular second person)./Bunları okursunuz(plural second person).
how to say.. we read this ?
"(Biz) bunu okuruz" :)
Isn't "You study this" also a possible answer?
Yep, just a missing alternative. It has been added. :)
Just for anyone reading this "Okumak" only means "study" as in "I study history." It has to do with what academic subject you are specializing in, not what subject's homework you are doing :)
I dont understan . why we say bu(n)u we must say bu(y)u
As they explained above. It is irregular (exception for bu, şu, o)
why is it bunu not bu? and what's the difference between them?
'Bu' is in nominative case(nominative is unmarked in Turkish), that means it is a subject. 'Bunu' is in accusative case and that means it is a (definitive) direct object.
"you read that" is a correct answer no ?
'that' means 'şu' or 'o'.
What is the different between Siz and Sen?
SEN means 1 person you talk with. Smth like "hey, you, boy, come closer". And SIZ means lots of people, like "hey, you, boyS..."
Why bunu not bu? What is the difference?
What is the different between bu and bunu? How do I know when to use bu and when to use bunu?
Why siz why not sen?
Siz is plural you (also, formal)
Sen is singular you (also, informal)
