просто vs только

prosto vs tol'ko — simply/just vs only/just

What it really means

Просто presents something as uncomplicated, merely the case, or an intensifier similar to “just/simply.” Только limits a choice or quantity and means “only,” though it can also soften a request (“just”). With не только ... но и, только marks the first member of a contrastive pair.

Examples in natural speech

Я просто устал после работы.
I am simply tired after work.
Это просто отличная идея!
It's just an excellent idea!
У меня только пять минут.
I have only five minutes.
Только позвони мне вечером.
Just call me in the evening.
Она не только читает, но и пишет.
She not only reads but also writes.

Common mistakes

Do not use просто when the intended meaning excludes alternatives: only five is только пять. Conversely, только пять does not mean “a mere five” in every context; просто пять can mean “simply five” without an exclusivity claim.

Memory tip

Просто removes complexity; только closes the door on other options.

Frequently asked questions

Why can both words translate as “just”?

English just covers simplicity, limitation, and a polite minimizer; Russian chooses просто for the first and только for the latter two.

Does только always precede what it limits?

Usually it is placed immediately before the limited word or phrase, but word order can shift emphasis.

What does просто так mean?

It means “for no particular reason” or “just like that,” not “only in that way.”
