Questions & Answers about Я не вижу разницы, хотя смотрю внимательно.
Why is it разницы (Genitive) instead of разницу (Accusative) here?
Because of the negated verb не вижу. In Russian, the direct object of a negated verb often takes the Genitive case instead of the Accusative. This is called the "Genitive of negation," and it is very common with abstract nouns like разница (difference) or verbs of perception like видеть (to see). This is a great chance to see the Genitive singular ending you're practicing in action!
What is the exact difference between вижу and смотрю?
It is the exact same difference as "see" vs. "look" in English. Видеть (вижу) refers to the physical ability or result of seeing, while смотреть (смотрю) refers to the deliberate action of pointing your eyes at something. So here, the speaker is performing the action of looking (смотрю), but failing to get the result of seeing (не вижу).
Could I just use но (but) instead of хотя (although)?
Yes, Я не вижу разницы, но смотрю внимательно makes perfect grammatical sense. However, хотя emphasizes the contrast a bit more strongly, showing that the lack of results is surprising despite the careful effort.
Is the word внимательно related to the Russian word for "attention"?
Yes! It shares the same root as the noun внимание (attention). So when you are looking внимательно, you are literally looking "attentively" or paying close attention.
