отвеча́ть vs реаги́ровать

otvechat vs reagirovat — answer/respond vs react

What it really means

Отвеча́ть means to answer a question, reply to a person, or respond to a request, call, or message. It normally frames the response as directed back to someone or something: отвеча́ть на вопро́с (“answer a question”) and отвеча́ть дру́гу (“reply to a friend”). It can also mean be responsible or accountable, as in отвеча́ть за прое́кт.

Реаги́ровать means to react or respond emotionally, physically, or behaviorally to a stimulus, event, or situation. It commonly takes на + accusative: реаги́ровать на крити́ку. It does not specifically promise an answer. Use отвечать when information or a reply is exchanged; use реагировать when describing a response to an impact or circumstance.

Examples in natural speech

Пожа́луйста, отвеча́й на вопро́сы по поря́дку.
Please answer the questions in order.
Она не отвеча́ет на мои́ сообще́ния.
She is not replying to my messages.
Он споко́йно реаги́рует на крити́ку.
He reacts calmly to criticism.
Де́ти бы́стро реаги́руют на измене́ния.
Children react quickly to changes.
Кто отвеча́ет за э́тот прое́кт?
Who is responsible for this project?

Common mistakes

Do not use реагировать на when you mean answering a question; say отвеча́ть на вопро́с. Conversely, отвечать за means “be responsible for,” not “react to.” Keep the government distinct: отвечать на or кому, but реагировать на.

Memory tip

Отвеча́ть sends a reply back; реаги́ровать shows what a stimulus causes.

Frequently asked questions

Does отвечать always mean “answer”?

No. It can also mean reply, be accountable, or be responsible, depending on its complement.

What case follows реагировать на?

На takes the accusative here: реаги́ровать на вопро́с, зву́к, or крити́ку.

Can both verbs translate as “respond”?

Yes, but отвечать implies a directed answer or reply, while реагировать covers broader emotional, physical, and behavioral reactions.
