"Call me when you finish the homework."

[kingundkong]

could you say: Ödevi bitince beni ara.

[LadyNurington]

You could say that sentence however it'd mean something else.

"Call me when his/her/its homework is finished."

[orde90]

Bitmek - to be finished (intransitive, it can't take objects).
Bitirmek - to finish sth (transitive)

[rfpl]

why is 'senin ödevi bitirince beni ara' wrong?

[amrbekhit]

Because you need to conjugate the "ödev" to match the "senin" :

Senin ödevini bitirince, beni ara

[aykabo]

It means "Call me when you finish YOUR work"

[daadaadaaren]

why is there an 'ev' in my suggested answer ? i don't see a 'home ' in the english translation

[AlexinNotTurkey]

"Homework" can either be ödev or ev ödevi :)

[gerbil67]

if there ıs no personal tense in these sort of sentences do you automatically assume its for sen/senin ?

[AlexinNotTurkey]

This is a command, you it must be in the second person. :)

[aykabo]

In fact there is personal tense in imperative:

sen ara
o arasın
siz arayın
onlar arasınlar

Why is "Sen ödevi bitirince, beni ara!" wrong?

[Selcen_Ozturk]

it is not wrong, it is a missing alternative. However, keep in mind that it would rarely be used

[aykabo]

The imperative "ara" already shows that it's second person (Sen). Since Turkish is a pro-drop language we do not need "Sen" at the beginning.

[snazzysusan]

Why do we use "beni" here instead of "bana"?

[AlexinNotTurkey]

The verb aramak used the accusative case. :)

[tunchozyur]

Odevini bitirdigin zaman beni ara
