Actually it is a perfectly fine form. It could be that someone was handed a glass of water that is a color they weren't expecting.
Dear DL staff, when the user/student is missing or using a wrong accent (e.g. viz instead of víz) you should replace the message "you have a typo" with "pay attention to the accents". Köszönöm szépen!
That wouldn't be true to the language. :c
Contrary to French, Spanish, or many other Romance languages, the accents aren't additions to the letters, but á, é, í, ó, and so on, are actual separate letters with their very own place in the Hungarian alphabet. The Hungarian alphabet has 14 different vowels, not just five or seven.
Does the Hungarian have the same meaning for 'grey water' as in English, where grey water means water that has been used and is not drinking water but dirty water that goes down the drain?
