Questions & Answers about İki arkadaş dün kavga etti ama bugün barışıyormuş.
How does barışıyormuş give the meaning of "I hear they are reconciling"?
This verb combines two important suffixes. The root is barış- (to make peace/reconcile). First, we add the present continuous suffix -ıyor (are reconciling). Then, we add the inferential suffix -muş. Adding -muş tells the listener that you didn't witness it yourself, but rather you heard about it or gathered it from context. So, barışıyormuş means "I hear/apparently they are reconciling."
Why is the plural suffix missing in İki arkadaş? Shouldn't it be arkadaşlar?
In Turkish, whenever you use a number or a quantity word before a noun (like iki for "two"), the noun must stay in its singular form. Saying iki arkadaşlar is grammatically incorrect, so it must be iki arkadaş.
If the subject is "two friends" (plural), why doesn't the verb barışıyormuş have a plural suffix (-lar) at the end?
Because the subject (İki arkadaş) already includes a number making it clear we are talking about more than one person, adding the plural suffix -lar to the verb (making it barışıyormuşlar) is optional. In fact, it is very common and natural to leave the verb in the singular form in these cases.
Why does "fought" translate to two words (kavga etti)?
