"Senki sem utazik fel arra a magas hegyre."

Translation: Nobody travels up that high mountain.

[kebukebu]

Does "sem" still translate explicitly as "not ... either" in a sentence like this, or does it roll up into the meaning of "senki"?

[gergo2]

The latter. For terms like "nobody", "nowhere", "never", etc., Hungarian uses double negation. "Senki" means nobody, but it must be used with "sem" or "nem" in a sentence. ("senki nem" means the same as "senki sem".)

[kebukebu]

Thanks!

[Ishana92]

is there any difference between senki sem and senki nem?

[RyagonIV]

No, they are used interchangeably.

[williamnw]

Up that is better than up onto that

[Elloughton]

I put "nobody is travelling up on that high mountain either", but there is no mention of "either" in the Duo translation: am I missing something?

[rrmmmm]

"high" should be accepted.
https://dictionary.cambridge.org/grammar/british-grammar/high-or-tall:
We use high for mountains and for things which are a long way above the ground. ... We use tall to describe things which are high and thin in their shape (e.g. buildings, trees).

[guntunge]

arra = MIA? in that direction?
a = that?

Nobody travels up in that/the direction of the high mountain?

fel arra -re is a little much information/direction?

[jzsuzsi]

In this sentence, arra has nothing to to with direction. It is az+ra

az a hegy that mountain

arra a hegyre onto that mountain

it is similar to: azon a hegyen, azzal a heggyel, etc.
