Usually adjectives come in masculine and feminine flavors and reflect the gender
of the noun they describe. Normally masculine adjectives end in an -o
and feminine adjectives end in an -a .
Some adjectives are invariable. They are the same regardless of whether they
describe a masculine or feminine noun. These end in an e or a consonant.
If a noun is plural then the adjective is also plural--an s is added
to the end.
If the adjective ends in a consonant, an es is added to the end to
make that adjective plural.
