Questions & Answers about На снегу ни одного заячьего следа.
How do we get the form заячьего from the noun заяц?
First, we form the base possessive adjective заячий (hare's). To make it genitive to agree with следа, we drop the -ий, add a soft sign (ь), and attach the genitive ending -его. This soft sign appears in all cases except the nominative masculine, showing that the stem itself is soft (заячь-).
Why is the genitive ending here spelled -его rather than -ого?
Possessive adjectives like заячий behave like soft-stem adjectives when they decline. Because the stem ends with a soft sign (ь), Russian spelling rules require the soft ending -его instead of the hard ending -ого. Remember that the г in this ending is still pronounced like a 'v' (-yevo).
Why are одного, заячьего, and следа all in the genitive case?
This sentence expresses the complete absence of something (not a single hare track). In Russian, negative expressions of presence or quantity, especially those built around ни одного (not a single), require the missing item to be in the genitive case.
Why does снег take the ending -у in на снегу instead of the normal prepositional -е?
Снег belongs to a specific, small group of masculine nouns that have a special locative case form. When indicating physical location with the prepositions в or на, these nouns take a stressed -у ending instead of the standard prepositional -е (just like в лесу or в аэропорту).
