"The new street leads somewhere else."

Translation: Ta nová ulice vede jinam.

[Thiccfoot]

When do you use "Jinde" and when "Jinam"?

[VladaFu]

It is the position vs. direction distinction. Something like English here vs. hither and there vs. thither. Jinde is a position (elsewhere) and jinam is a direction (like elsewhither, which is extremely rare).

[Stephen900455]

Although people do say "somewhere else", more often people say "elsewhere".

[VladaFu]

And indeed, that is accepted too.

[Alex.Eisner]

"Ta nová ulice vede nikam jinam." Was correct, but with a typo. How do i know if i should use "nikam jinam" or just "jinam"?

[VladaFu]

does not anywhere else - nevede (nIkam) jinam

leads somewhere else - vede (nĚkam) jinam

Both někam and nikam are optional here.

[Alex.Eisner]

Oh I see. First I mistakenly used nIkam instead of nĚkam, which was the typo.

Are there instances when jinam requires the use of nikam/někam?

[VladaFu]

I do not think so.
