Russian мочь

Some Russian words (or word constructions) govern other words in Russian sentences causing changes to their endings: Russian nouns, pronouns, adjectives and numerals decline and they also agree with each other in gender (masculine, feminine, neuter), number and case (nominative, genitive, dative, accusative, instrumental, prepositional). Russian adverbs, conjunctions, interjections, prepositions stay the same. Russian verbs conjugate and have only three tenses: present, past and future but majority have two verbs to express the same action. Russian imperative is not difficult but verbs of motion & position are.
