In this exercise we will practice these noun cases:  

Dative case: -e, -a (means to)

Locative case: -de, -da, -te, -ta (means in, at, on)

Ablative case: -den, -dan, -ten, -tan (means from)  

It is the verb that determines which case we should use.  For instance, if you would say "I´m going" (gidiyorum) you would use the dative case because you are going to. If you would say "I´m living" (yaşıyorum), you would use the locative case because you are living in. If you are coming you are coming from, therefore the ablative case will be used with that verb.    

In this exercise you need to know the meanings of these verbs:  

gitmek: to go (use dative)

yaşamak: to live (use locative)

gelmek: to come (use ablative)  

Add the correct case suffix:  

Example:

This is the given sentence: Ben Ankara´... geliyorum.

This is your answer: Ben Ankara´dan geliyorum.
