Learn Turkish: Annem akşam fasulye pişirdi, çok lezzetliydi. - My mother cooked beans in the evening; they were very delicious.

In Turkish, common time periods like sabah (morning), akşam (evening), and gece (night) do not take the locative case suffix -da or -de (in/at/on) when describing when an action happens. You just use the plain word.

The translation says 'beans' (plural), but fasulye lacks the plural suffix -ler. Why?

When talking about a general category of food or a non-specific direct object, Turkish keeps the noun singular. Saying fasulyeler would mean specific, individual beans, rather than the meal as a whole.

I've seen the verb pişmek for 'to cook'. Why is it pişirmek (pişirdi) here?

Pişmek is used when the food itself is cooking. When a person is cooking the food, you must use pişirmek. Since the mother is doing the action to the beans, we use the past tense of pişirmek, which is pişirdi.

Why is there a -y- in lezzetliydi?
