Learn Turkish: Özetle, su aygırının bütün gün suda bekliyor olması normal. - In summary, it is normal that the hippopotamus is waiting in the water all day.

While beklemesi means 'its waiting' or 'that it waits', combining the continuous finite verb bekliyor with the verbal noun olması emphasizes the ongoing, continuous nature of the action. It specifically highlights 'the fact that it is currently waiting'. This is the standard way to bring the continuous aspect into a nominal clause.

Why does su aygırı take the genitive case suffix -nın to become su aygırının?

Because it is the subject of the nominal clause bekliyor olması. In Turkish, when a whole clause acts as a noun (literally 'the hippopotamus's being waiting'), the subject of that action takes the genitive case, and the noun-verb itself takes a possessive suffix (the -sı on olma).

How does the word özetle get its meaning of 'in summary'?

It is formed by combining the noun özet (summary) with the suffix form of ile (-le, meaning with or by). Literally meaning 'with a summary', it is the standard adverbial way to say 'in summary' or 'to sum up' in Turkish.

Does beklemek just mean 'to wait for something' here?

Not quite! While beklemek heavily translates to 'to wait', Turkish speakers frequently use it to describe staying, standing by, or spending time in a spot without necessarily anticipating anything. Here, it perfectly describes the hippo just 'hanging out' in the water all day.
