Can you help me why isn't "I see the mice" acceptable?
"I see the mice" would be "Vidím TY myši".
It's accepted when I tried just now (Nov. 11th 2020)
Is the word mouse/mice masculine or feminine? Mys ends in a consonant, so I assumed it was masculine.
Myš is feminine.
Which pattern does it follow for noun endings?
kost, or whichever we used instead for the -i sing. genitive and -ím pl. genitive
