Learn Turkish: Gagası sarı kuğu her zaman nehrin kenarında dinlenir. - The yellow-beaked swan always rests by the edge of the river.

This is a special type of compound adjective using the formula: Noun + 3rd person possessive + Adjective. Gaga means beak and the -sı is the possessive suffix (its). Literally, gagası sarı kuğu means "the swan whose beak is yellow." This is a very common way in Turkish to describe physical traits, similar to saying saçı uzun for "long-haired".

Why is the word for river spelled nehrin instead of nehirin?

The root word is nehir (river). It belongs to a group of words (often loanwords, like şehir or isim) that drop the vowel in their final syllable when a suffix starting with a vowel is added. Here, adding the genitive suffix -in causes the second i in nehir to disappear, resulting in nehrin.

Can you break down the suffixes in kenarında?

The base word is kenar (edge). To say "the river's edge," we use a possessive construction: nehrin kenar-ı. Then we add the locative suffix -da (at/by). Whenever you attach a spatial case marker to a 3rd person possessive suffix, Turkish requires the buffer letter -n-. So it perfectly builds up as kenar-ı-n-da.

Why is the aorist tense used in dinlenir instead of the present continuous dinleniyor?
