In Portuguese grammar, plural nouns generally end in -s, just as they do in English. However, there are certain rules and exceptions to be aware of when forming the plural. For example, if a noun ends in -ão, it may change to -ões, -ãos, or -ães. Additionally, some nouns will undergo small spelling modifications when changing to their plural forms. In this exercise, you will practice forming the plural of various Portuguese nouns. Remember that adjectives must agree in number and gender with the nouns they modify, so you will need to make a few adjustments there as well. Good luck!
