Questions & Answers about O sol é amarelo.

Why is there a definite article o before sol?

In Brazilian Portuguese you almost always use a definite article before a common noun, even when talking about general things. With sol (sun), you say o sol because:

• Portuguese requires articles before nouns more often than English does.
• Celestial bodies typically take an article: o sol, a lua, o mar.
• Omitting the article (sol é amarelo) sounds unnatural in most contexts.

What does the accent on é mean? How is é different from e?

• é (with an acute accent) is the third-person singular present form of the verb ser, meaning “is.”
• The accent shows it’s pronounced with an open /ɛ/ sound: é.
• Without the accent, e (pronounced /i/) is the conjunction “and.”

Why do we use ser (é) here instead of estar (está)?

Portuguese distinguishes between permanent traits and temporary states:

• Ser describes inherent or long-lasting qualities (color, identity, origin).
• Estar describes temporary conditions or locations.
  Since the color of the sun is considered a permanent characteristic, you use é (from ser).

Why does the adjective amarelo come after sol instead of before?

Adjective placement in Portuguese usually follows the noun:

• Standard order: noun + adjective (e.g., casa grande, carro rápido).
• Putting an adjective before the noun can add emphasis or be poetic, but it’s not the norm for simple descriptive sentences.

Why is amarelo in its masculine form? What if the noun were feminine?

Adjectives must agree in gender and number with the nouns they modify:

• Sol is masculine singular → amarelo (masculine singular).
• If the noun were feminine (e.g., flor), you’d say a flor é amarela (feminine singular).

How would I make this sentence negative?

Place não before the verb:

• Affirmative: O sol é amarelo. (“The sun is yellow.”)
• Negative: O sol não é amarelo. (“The sun is not yellow.”)
