Questions & Answers about По-моему, он прав.

What does по-моему mean, and how is it different from just saying я думаю?

По-моему means in my opinion, as for me, or to my mind.

So:

• По-моему, он прав. = In my opinion, he is right.

It is very common in Russian and often sounds a bit more natural and idiomatic than always saying я думаю.

Compare:

• Я думаю, он прав. = I think he is right.
• По-моему, он прав. = In my opinion, he is right.

The difference is small, but по-моему sounds a little more like you are giving your personal view, while я думаю focuses more on the act of thinking.

Why is there a hyphen in по-моему?

Because по-моему is a fixed adverbial expression, and Russian writes forms like this with a hyphen.

This pattern is common with expressions such as:

• по-моему = in my opinion
• по-твоему = in your opinion
• по-нашему = in our opinion / in our way
• по-русски = in Russian

So the hyphen is just part of the standard spelling here. You should learn по-моему as one set expression.
