i have a strange question: if stroj, strom were animate (eg, specific races of creatures in some fantastic movie), their plural would be stroji, stromi?
Very rarely you can find "stromové" and probably "strojové".
Why isn't it "Stromy jsou dobrý?" as trees are masculine, thanks!
You need plural. Dobrý is singular "Strom je dobrý.".
Stromy are inanimate, despite some people's opinion :)
