verb aspect	вид глагола (In Russian, verbs have two "aspects" (вида): imperfective (несовершенный вид) and perfective (совершенный вид). The choice between these two aspects affects the meaning of the verb in terms of its completeness, duration, repetition, and other nuances. For example, "читать" (imperfective) means "to read" in a general or ongoing sense, while "прочитать" (perfective) means "to read" with a sense of completion, like "to read through" or "to finish reading." Beloshapkina)
