On Kommersant FM radio this morning I heard a mention of огосударствление банка, the nationalisation of a bank. This is a new addition to my mental list of Russian abstract nouns made of three elements: the prefix о- or об-; the central root, which can be based on a noun or adjective (in this case государство, state); and the suffix -ение or -ление. Here are some others:
– обновление, renewal, update
– очернение, blackening
– озеленение, greening, the planting of trees and other greenery
– ограбление, robbery
I know there are loads more but I can’t think of any just now. If you know any more then be sure to mention them in the comments!
