Can someone please explain the distinction between: biri and birisi?
There is no difference
Why is there no 'ki' after sanirim?
I have the same question.
"Sanırım", can it be at the end of the sentence?
I guess, but it wouldn't really sound all that natural. Turks always use it at the beginning
Yes, you can use at the end of sentence.
Is there a difference between "sanırım" and "galiba" ?
there is no difference at all in the meaning. the only difference is that galiba is more informal.
Yep, "sanırım" is more like "I guess" and "galiba" is more like "I think..." Also "galiba" normally goes at the end of the sentence :)
Sanmiyorum. Ben galiba kullandim, yanlis cikti.
So can we use galiba in this sentence?
why not: sanirim kimse masayi silmis?
"Birinin masayı sildiğini tahmin ediyorum" is one of the accurate answers.
Why is 'biri' used instead of 'bir'?
