Questions & Answers about Кольцо удвоения находится снаружи кольца утроения.

What cases are the nouns in, and why?

Here is the case breakdown:

• Кольцо — nominative singular
  It is the subject of the sentence.

• удвоения — genitive singular
  It depends on кольцо and means of doubling.

• кольца — genitive singular
  It comes after снаружи, which takes the genitive here.

• утроения — genitive singular
  It depends on кольца and means of tripling.

So the structure is basically:

• Кольцо удвоения = the ring of doubling
• снаружи кольца утроения = outside the ring of tripling

Why are удвоения and утроения in the genitive instead of being adjectives?

Russian very often uses noun + genitive where English uses either:

• of
• or a noun used like an adjective

So:

• кольцо удвоения literally means ring of doubling
• кольцо утроения literally means ring of tripling

In English, we may prefer doubling ring and tripling ring, but Russian commonly expresses that relationship with the genitive.

Also, удвоение and утроение are nouns, not adjectives, so they do not agree with кольцо in gender or number.
