Questions & Answers about В озере глубже, чем в реке.
Russian often omits the present-tense form of to be (есть) in ordinary statements. So the meaning is understood as (It is) deeper in the lake than in the river without any verb being written.
Глубже is the comparative form of глубокий (deep) / глубоко (deeply). In this sentence it functions like a predicate meaning deeper (i.e., the depth is greater). Russian commonly uses the comparative like this without an explicit noun: (там) глубже = it’s deeper (there).
Because the sentence compares depth in places, not the two bodies of water as objects.
- В озере глубже, чем в реке. = It’s deeper in the lake than in the river (talking about the water depth there).
If you say: - Озеро глубже, чем река. = The lake is deeper than the river (treating them more like objects being compared overall).
Both are in the prepositional case because of the preposition в meaning in (location).
- в озере (озеро → озере)
- в реке (река → реке)
Usually в озере is correct for being in the lake (in the water / within the lake). На озере is possible but tends to mean at the lake / by the lake / on the lake (area/shore/ice) depending on context. For talking about depth of the water, в озере is the normal choice.
Чем introduces the second part of a comparative: deeper than…
Pattern: (A) + comparative + чем + (B)
So глубже, чем в реке = deeper than in the river.
In this kind of clear comparison, a comma is normally used: глубже, чем…
In some short or very tightly connected phrases, you may sometimes see no comma, but for learners it’s safest to treat comparative + , чем as the standard written form.
It’s an impersonal construction: the subject is not stated. The idea is the depth (or the water) is greater there. Russian often expresses this as (там) глубже without naming what is deep.
Yes. Common options are:
- В озере там глубже, чем в реке. (less natural, context-dependent)
- В озере глубже, чем в реке. (most neutral)
- В озере глубже, чем в реке, там мельче. (if contrasting places)
Most of the time там is unnecessary because в озере / в реке already specify location.
It can be shortened if the context makes it obvious:
- В озере глубже, чем в реке. (full, clear)
- В озере глубже, чем в ней. = …than in it (the river)
But repeating в + location is very common and sounds natural.
You can modify the comparative:
- В озере намного глубже, чем в реке. = much deeper
- В озере чуть/немного глубже, чем в реке. = a little deeper
