Vrea cineva sa mă ajute cu gramatica limbii române? Well... we have 3 gens: feminine, masculine and neutral. Of course, to find out at which gen is every word, you have to check the dictionary, but the rule is simple. The feminine is formed so: for singular "o" and for plural "două". O casă, două case. O masă, două mese. When we are talking about masculine we count "un băiat", "doi băieți". When it's about neutral, the singular is "un" and the plural is "doua". Maybe it seems to be strange, but there are many nouns at neutral. One example is "un pat", "două paturi"... or "un vis", "două vise". I hope you understand. :)
