Is sounds like 'swine', if that helps.
Would "is THAT a pig" also work for this?
That would rather be "то свиня?"
Why is the sentence "Is it a hog?" not accepted?
Hog = кабан
Does this imply gender?
Couldn't this be "this pig?" as well?
No, it would be Ця свиня
Oh, ok. So це is like if you point at something and say "this is a cat/a house" etc., but if you want to say "this cat is green", "this house is on fire" etc. it has to match the gender of the word?
You are right. But if you were to match it to a noun of the neuter gender it would also be це: це молоко (this milk)
I see. Thank you!
