Gender categoristion of Adjectives (Masculin/Feminine and Plural)

Gender/Number
•    All French adjectives have four forms: masculine, singular; feminine, singular; masculine, plural; and feminine plural. The following are the rules for creating each form:
o    Masculine singular: generally, you will be given the masculine, singular form of an adjective in the dictionary, so you make no changes.
o    Feminine singular: In order to make a masculine adjective feminine, you simply add an "e" at the end.
** if the adjective already has an unaccented "e" at the end, do not add anything.
o    Masculine plural: generally, you will add an "s" to the end of your masculine, singular noun; there are some irregulars.
** if the adjective already ends in an s or x, do not add anything**
o    Feminine plural: add an "s" to the feminine form.
** if the adjective already ends in an s or x, do not add anything***
