1. Gender and Adjective Agreement
Nouns and pronouns in Spanish are divided into gender.
Masculine for men and boys. EX: amigo, Juan, él
Feminine for women and girls. EX: amiga, Lisa, ella

2. Adjectives
Adjectives describe nouns. They have different forms that match with the noun in gender and number.
The masculine form of most adjectives ends with “o”. EX: Richie es romántico.
The feminine form of most adjectives ends with “a”. EX: Betty es bonita.

3. Adjectives that end with “e” are gender neutral
Adjectives that end with “e” are gender neutral. EX: José es inteligente. Jenna es inteligente.
Adjectives that end in consonants are gender neutral unless referring to a feminine noun and they end with “-or” or are adjectives of nationality. EX: Tina es trabajadora. María es española.

4. Adjectives agree with nouns in number.
Adjectives describing one person or thing are singular. Adjectives describing more than one person or thing are plural.
If the singular form ends in a vowel, add “s” to make it plural. EX: Pat es alto.  Pat y Steve son altos.

5. If an adjective ends in a consonant, add “es” to make it plural
If an adjective ends in a consonant, add “es” to make it plural. EX: Ricky es intelectual.  Ricky y Dana son intelectuales.
We always use the masculine plural form to describe a group of masculine and feminine nouns. EX: Ana y Tom son románticos.
