вначале vs сначала

vnachále vs snachála — at the beginning vs first/at first

What it really means

Вначале locates something at the beginning of a period, event, or text. Сначала means “first” in a sequence, “at first” before a later change, or “from the beginning,” and is the usual word for ordering actions.

Examples in natural speech

Вначале фильма звучит тихая музыка.
At the beginning of the film, quiet music plays.
Сначала прочитай инструкцию.
First read the instructions.
Вначале было трудно.
At the beginning, it was difficult.
Сначала я не понял, а потом разобрался.
At first I did not understand, but then I figured it out.
Вначале урока повторим слова.
At the beginning of the lesson, we will review the words.

Common mistakes

Do not use вначале to give the first step in instructions: *вначале прочитай инструкцию is less idiomatic than сначала прочитай инструкцию. Use вначале to point to the opening part of something, especially with a genitive phrase such as вначале урока.

Memory tip

Вначале points to the opening page of an event; сначала points to step one on a to-do list—or to an earlier opinion that later changed.

Frequently asked questions

Can both words mean “at first”?

Often yes in a temporal context: вначале было трудно and сначала было трудно. Сначала is more common when a contrast follows, such as сначала я сомневался, потом согласился.

Which word should I use in a sequence of instructions?

Use сначала: Сначала включите компьютер, потом откройте программу. It introduces the first action, not merely the beginning section of an event.

Why does «вначале урока» use the genitive?

Вначале combines naturally with a genitive noun to name the period whose opening is meant: вначале книги, вначале встречи, вначале года.
