"Hetvenhárom új szálloda áll a híres tenger mellett."

Translation: Seventy-three new hotels stand beside the famous sea.

Ok, after doing a whole bunch of course, I absolutely cannot understand when 'mellett' is 'beside' 'next to' or 'by!' Any help would be very much appreciated :)

[linguafiqari]

It's all of them, but not all have been input into the system.

Thanks, now I feel like much less of an idiot :)

Another concern is why áll is not before
mellett here

[mizinamo]

mellett is a postposition so it has to come right after the noun phrase it modifies (a híres tenger).

Just like you can't separate "beside" and "the famous sea" to write something like "Seventy-three hotels beside stand the famous sea" in English.
