начинать vs начать

nachinat vs nachat — begin as a process/repeated action vs start once

What it really means

Начина́ть is imperfective and describes starting as a process, a repeated habit, or an action viewed without its endpoint. На́чать is perfective and presents one start as a completed event: "Урок начался" (The lesson started). Both can refer to the future, but начать makes the beginning a single result.

With a second verb, начать commonly takes the infinitive: начать работать (start working). Начинать can do the same when the focus is habitual or ongoing: начинать день с кофе (start the day with coffee). The perfective form is especially natural for a one-time instruction or decision.

Examples in natural speech

Я начинаю работать в девять.
I start work at nine.
Каждый урок мы начинаем с повторения.
We start every lesson with revision.
Фильм начался в восемь.
The film started at eight.
Давайте начнём урок.
Let's start the lesson.
Она начала читать новую книгу.
She started reading a new book.
Он часто начинает говорить слишком быстро.
He often starts speaking too quickly.

Common mistakes

Do not use начать for a habitual schedule when you mean the repeated routine: "Каждый день я начинаю..." is natural. Conversely, for a single completed beginning, "Встреча начиналась в десять" describes the process or scheduled timing, while "Встреча началась в десять" says it actually started then.

Memory tip

Начинать is starting as a routine or process; начать is one start viewed as a result.
