Learn Turkish: Hemşire reçetemi bugün almamı istedi. - The nurse wanted me to get my prescription today.

This is an indirect request using the short verbal noun -ma. We take the verb root al, add the verbal noun suffix -ma, then the possessive suffix -m (my), and finally the accusative case -ı. Literally, it means "my getting". Combined with the main verb, almamı istedi translates to "she wanted my getting" or "she wanted me to get".

Why does almamı need the accusative case suffix (-ı) at the end?

The main verb istemek (to want) requires a specific direct object to be in the accusative case. Here, the specific thing the nurse wants is "my getting" (almam). To make it the direct object of istedi, we must add the accusative -ı.

Why does reçetemi also have an accusative suffix (-i)?

reçetemi is the direct object of the verbal noun alma (getting). Since it refers to a specific thing ("my" prescription), it needs the accusative case. It breaks down as reçete (prescription) + -m (my) + -i (accusative).

Is it normal to have two accusative endings in the same sentence, like in reçetemi and almamı?
