"Medvědi jsou těžcí, ale ne pomalí."

i think the adjectives should be těžké and pomalé

[Jamie08MD]

"Medvěd" is a masculine animate noun -> the adjective has to have masculine animate ending "těžký" a "pomalý". However, here you have "medvědi", which is plural; and the masculine animate plural ending for adjectives in nominative is "těžcí/pomalí".

"Těžké/pomalé" would be the ending for masculine inanimate nouns or feminine nouns.
