"Ciocanul lui este greu."

Translation: His hammer is heavy.

[Alpenpeilchen]

Thor, is that you?

[snayar]

why is "his hammer is hard" not correct?

[abcdefg-1]

Because "greu" means "hard" as in "difficult."

[FilipFilip17]

I think that "hard" is "tare".

[Artie324384]

These makes fists are NOT the hammer
