Russian Word of the Day

The Russian word for night is ночь. You may remember that the Spanish word for night is noche, which might lead you to wonder whether Spanish borrowed it from Russian or vice-versa. The answer is neither. Russian ночь and Spanish noche are cognates. In historical linguistics ‘cognates’ are words that descended from the same source many years ago, and due to the fact that they have a common ancestor, they still have a resemblance to each other.¹ Thus German nacht and English night are also cognates with Russian ночь because they are all descended from the same Proto-Indo-European word.

Ночь is a third-declension noun, which means it declines like this:

Many of the uses of ночь are similar to the use of night in English:

The most famous nights of Russia are the white nights белые ночи. Officially Moscow and Petersburg are too far south to have proper white nights, but during the two weeks on either side of the summer solstice Petersburg's nights are very white indeed, and the city hosts a world-famous celebration that attracts artists and celebrants from all over the world:

When discussing time by the clock, there is a difference between Russian and English. In English night is sometimes conceived of as the time between sundown and midnight. In Russian ‘night’ is the time between midnight and roughly 4:00 a.m. So instead of saying “3:00 in the morning” the Russians say “3:00 at night”:

Thus:

¹ Outside of historical linguistics sometimes people use ‘cognate’ to mean a word that is superficially similar to another word in both sound and meaning. In that sense English television and Spanish televisión may be called cognates, but that's a sloppy use of the word. In all likelihood the Spanish word is a direct borrowing from French or English.

² There is some variation here. Some people will say четыре часа ночи. I wouldn't be surprised if the time of year actually affects this as well, with more people saying утра in the summer when it gets light earlier, and ночи in the winter when it stays dark later. A quick Google search also shows variation with five a.m.
