"Медведь больше волка."

Translation: A bear is bigger than a wolf.

[LangForThought]

I was taught to say "Медведь больше, чем волк"

[JanisaChatte]

Both ways of saying it are correct.

[RandomCanadian12]

is there a difference between "more" and "bigger" in russian?

[QurtQurt]

No. Both translate as "бо́льше".

[RandomCanadian12]

so, это больше волка means "this is bigger than a wolf" while это больше волк means "this is a bigger wolf"?

[QurtQurt]

"Это бо́льше волк" doesn't make sense.

"This is a bigger wolf." ...I don't understand it because it looks like an incomplete sentence.

[Joseph_Pate]

This is a wolf, and that is a bigger wolf.

Это волк, а тот ____ волк.

[Shady_arc]

"..., а это волк побольше" or ", а это более крупный волк" would work.

Does this mean that comparative adjectives induce the accusative?

[Jenz114]

The comparative adjective gives us two options.
Медведь больше, чем волк.
Медведь больше волка.
In the example where чем is omitted, the second noun is in the genitive case. It just so happens that animate nouns like волк are declined just like the accusative.

[InvincibleTitan]

I put 'the bear is bigger than a wolf'. Is this not correct?

[Shady_arc]

In this sentence, any combination of a/the bear and a/the wolf is accepted.
