Questions & Answers about Разве ты командуешь проектом и диктуешь правила?
Why do the verbs командуешь and диктуешь have that -уешь ending instead of keeping their full infinitive stem?
Their infinitives are командовать (to command) and диктовать (to dictate). This is a special rule for verbs ending in -овать or -евать. When you conjugate them in the present tense, that -ова- or -ева- suffix mutates into a single -у- or -ю-. Then you just add the regular endings, giving us ты команд-у-ешь and ты дикт-у-ешь.
Why is the word проект (project) in the instrumental case (проектом) here?
The verb командовать (to command or be in charge of) requires the instrumental case for the thing or people you are commanding. You will see this pattern with several other Russian verbs related to managing, leading, or controlling, such as руководить (to manage) and управлять (to direct).
Why is правила not also in the instrumental case like проектом?
Правила (the rules) belongs to the second verb in the sentence: диктуешь (you dictate). Unlike commanding, dictating takes a standard direct object in the accusative case. Since правило is a neuter noun, its accusative plural form правила looks exactly identical to its nominative plural form.
