сначала vs сперва

snachala vs sperva — first/at first vs first/to begin with

What it really means

Сначала is the standard adverb for the first step in a sequence and for “at first,” often contrasting with потом or затем. Сперва has the same basic temporal meaning but is more conversational, slightly old-fashioned, or stylistically marked in some contexts. Both are written as one word and do not themselves determine comma placement.

Examples in natural speech

Сначала прочитай инструкцию.
First, read the instructions.
Сначала он молчал, потом ответил.
At first he was silent, then he answered.
Сперва выпьем кофе.
First, let’s have coffee.
Сперва я не понял вопроса.
At first I did not understand the question.
Сначала нужно проверить данные.
The data need to be checked first.

Common mistakes

Do not treat сперва as a formal upgrade: it can sound literary or colloquial depending on context. Do not add a comma automatically after either adverb, and do not confuse сначала with the noun phrase «с начала» (“from the beginning”) when the separate spelling is required.

Memory tip

Сначала is the unmarked sequence marker; сперва tells the same story with a more marked voice.
