Lists present tense conjugations (only first and second person singular) of Russian verbs. If you know the infinitive as well as the first and second person singular forms of a verb in Russian, you will then usually know the whole verb. Third person singular as well as all of the plural forms of a verb in the present tense are based off of second person singular. The imperative forms are also based off of second person singular. The past tense is based off of the infinitive, and the future tense is based off of the infinitive. First person singular isn’t based off of anything so that’s why you have to memorise it separately.
All you generally need for a verb is the infinitive, the first person singular and the second person singular in the present tense to understand the whole verb (but there are still occasional exceptions).
