On an inconceivable infinitive and on the declination of some Russian nouns

In the article we regard nonstandard word-inflexion features of four Russian words: the alternate form vygryzti together with a standard infinitive vygryzt’, the partitive genitive of a neutral noun pivko, the genitive plural form razov of the noun raz, and the preservation of mobile vowel in plural forms of the noun ljubov’. We discuss the possible lexicographic representation of these features.
