Questions & Answers about Ormandaki kuşlar sabah ötebilir.
How do we know ötebilir means "might chirp" (possibility) and not "can chirp" (ability)?
The suffix combination of -ebil plus the aorist -ir can express either ability ("can") or possibility ("might" or "may"). You have to rely on context. Since birds inherently know how to chirp, stating they can chirp is just stating the obvious. Therefore, the listener naturally understands this as a possibility: they might chirp.
Why does the possibility suffix use the aorist tense (-ir) here?
When expressing a guess or probability that something might happen, Turkish almost always pairs the -ebil / -abil suffix with the aorist tense. This formula (Verb + -(y)Abil + Aorist) is the standard way to translate "might" or "may" into Turkish.
Why is -ki attached to ormanda? Couldn't we just say "Ormanda kuşlar..."?
Ormanda simply means "in the forest." By adding the suffix -ki, you turn that location into an adjective that directly describes the noun next to it. Ormandaki kuşlar means "the birds that are in the forest." If you just said Ormanda kuşlar sabah ötebilir, it would slightly change the focus to "Birds might chirp in the forest in the morning."
Can the verb ötmek be used for humans singing or talking?
