Combinations with -ever:

For whatever reason you might have taken this path, it leads to nowhere.

Whereever you might go (i will follow)

However hard you try (you will fail)

For whatever reason you might have taken this path, it leads to nowhere.

Ne (hangi) sebeple bu yolu almýþ olursan ol, hiç bir yere götürmez.

Whereever you might go (i will follow)

Nereye gidersen git takip edeceðim (or peþinden geleceðim)

However hard you try (you will fail)

Ne kadar denersen dene baþaramayacaksýn.

 I agree with Meltem for the second and third on, but the first one could also be said in a different way:

Her ne sebeple (bu yolu) seçmiþ olursan ol, bu yol seni hiç bir yere götürmez..

Thanks mltm and Merih. You´re a great help!

 Yes I think yours sounds much better. In fact, I did not like mine, but I tried to stay as close as possible to the original one so that he understands.

 yeah I know.. I was thinking the same thing.. yours was a very correct translation, but missing something.. thanks anyway
