Questions & Answers about Bana bağıracak kadar kaba.
How does the grammar work here to mean "enough to yell"?
This sentence uses the pattern verb + -(y)AcAk kadar. The suffix -acak usually marks the future tense, but here it combines with kadar (up to / as much as) to express a degree or limit. Literally, bağıracak kadar means "to the degree that [he] will yell". When placed before an adjective, it translates nicely to "[adjective] enough to [verb]".
Why does the sentence use bana (to me) instead of beni (me)?
The verb bağırmak (to yell / shout) always takes the dative case. In Turkish, you direct your voice to or towards a person, so you must use bana rather than the accusative beni.
Where is the "he is" part of the sentence?
The subject "he" (or "she") is dropped because it's understood from context, which is very common in Turkish. The "is" is represented by the zero copula: in the third-person singular, the present tense "to be" suffix (-dır / -dir) is frequently left off. So, the word kaba alone carries the meaning "[he] is rude".
Why does the adjective kaba come at the very end of the sentence?
