sentences:  Most nouns have no gender, though there are different words for females and males in some cases ("ama", "mother"; "aita", "father"; "guraso", "parent").Some words are differentiated according to gender, like in the English language ("akt+oresa", "act+ress"; "akt+ore", "act+or"), but they are not the main rule.For animals, there are particles ("oil+o", "hen"; "oil+ar", "cock"; "hartz eme", "female bear"; "hartz arra", "male bear") or different words ("behi", "cow"; "zezen", "bull").
