Kıtapmim vermesen

How to simulate this Turkish sentence in English?

I my book give him

I book my give him

My book give I him?

It is "Ona kitabımı veririm" and in English it is "To him, my book I give."

Or you can also say "Kitabımı ona veririm" and it´s "My book, to him I give."

My thoughts on your questions (but I am not a Turk).

I give him my book

is it valid to express it in Turkish like this?

Kıtapmim vermesen This is wrong, because ...

him = o

to him = ona

book = kitap

my book = kitap + ım = kitabım (p mutates to b)

when using the verb ´vermek´ (to give) the object (my book) has an accusative suffix added and becomes kitabımı ver.....

Generally Turks use present continuous tense (iyor) for actions that are happening now, and aorist tense (ir) for actions that occur regularly.

I am giving him my book = Ona kitabımı veriyorum.

I gave him my book = Ona kitabımı verdim.

I will give him my book = Ona kitabımı vereceğim.
