Questions & Answers about Межзрачковое расстояние и внутриглазное давление измерили.
Why is there no subject in this sentence?
Russian often leaves out they when the subject is unknown, unimportant, or obvious from context.
So измерили literally means they measured, but here it is better understood as:
- They measured the interpupillary distance and intraocular pressure
- or in more natural English, The interpupillary distance and intraocular pressure were measured
This is very common in medical, official, and procedural language.
Why is the verb измерили plural?
Because the verb agrees with an implied plural subject: they.
It does not agree with расстояние or давление here, because those words are the things being measured, not the doers of the action.
So:
- измерили = they measured
- plural because the hidden subject is plural
Are межзрачковое расстояние and внутриглазное давление nominative or accusative?
They are accusative, because they are the direct objects of измерили.
However, for inanimate neuter singular nouns, the accusative looks exactly like the nominative. So:
- расстояние = nominative or accusative
- давление = nominative or accusative
That is why the form looks unchanged.
How do we know these nouns are objects and not the subject?
