Nouns and Adjectives Change Based on Gender Not Verbs

In Spanish, it's the nouns and adjectives that change based on gender, not the verbs.

Key points:

Nouns

Nouns have gender, either masculine or feminine:
- Masculine nouns typically end in -o (e.g., niño - boy).
- Feminine nouns typically end in -a (e.g., niña - girl).

Adjectives

Adjectives also change to match the gender of the noun they describe:
- El coche rojo (the red car - masculine) vs. La casa roja (the red house - feminine).
- Niño alto (tall boy), Niña alta (tall girl)
  - "alto" (tall) changes to "alta" to agree with the feminine noun "niña".

Some adjectives do not change

In Spanish, most adjectives change based on the gender of the noun they describe, but some adjectives do not.

Niño inteligente (smart boy), Niña inteligente (smart girl)
- In this case, "inteligente" stays the same for both genders.

Rule of Thumb:

Adjectives ending in -o usually change to -a for feminine nouns (e.g., alto → alta).
Adjectives ending in -e or consonants generally stay the same for both genders (e.g., inteligente, feliz).

Verbs

Verbs, on the other hand, do not change based on gender. Verbs only change based on the subject's person (I, you, he, she, etc.) and tense (past, present, future, etc.).

For example:

Yo hablo (I speak) – The verb hablo doesn't change regardless of whether the subject is male or female.
Ella corre (She runs) vs. Él corre (He runs) – The verb corre (runs) stays the same for both.

So, in Spanish, gender affects nouns and adjectives, while verbs are only affected by person and tense.
