Welcome to the forum. This group is happy to have new members who want to learn a language (either Spanish or English). You are probably referring to masculine vs. feminine nouns I suppose. Most masculine nouns end in -o and most feminine nouns end in -a, -sión, -ción, -dad, -tad, -tud or -umbre but, there are quite a few exceptions and there are good reasons for a lot of the exceptions.
