"The girl steps out onto the street and walks down to the water."

Translation: A lány kilép az utcára és lesétál a vízhez.

[GerSzej]

could we use vizre also?

[RyagonIV]

It would call for Jesus-like qualities. Or a boat.

[mizinamo]

"onto the water"? That doesn't seem to be what the English sentence is saying.

[vvsey]

Nor is the Hungarian sentence. If you walk, you can walk "a vízhez". But, if it is not meant quite literally, -ra/-re is also used sometimes. Folyóra, tóra, Balatonra, stb. It may or may not mean the water body itself.

[Krisbaudi]

What is wrong with lemegy - for walk down?

[RyagonIV]

Nothing in principle, but megy is a much more general word than sétál. Usually this course goes for these translations: megy - to go; sétál - to walk.
