What do cheio and vazio mean?
Cheio means full. Use it when something contains a lot of something else, is occupied, or reaches capacity.
Vazio means empty. Use it when something has little or nothing inside, is unoccupied, or lacks content.
Basic grammatical notes
Both cheio and vazio are adjectives and must agree in gender and number with the noun they describe.
Masculine singular: cheio, vazio
Feminine singular: cheia, vazia
Masculine plural: cheios, vazios
Feminine plural: cheias, vazias
How to form simple sentences
Beginner-friendly sentence structure: subject + estar + adjective. Use the verb estar to describe a current state.
Examples:
O ônibus está cheio.
A garrafa está vazia.
Os bancos estão cheios.
As caixas estão vazias.
Common short phrases and signs
Many everyday signs and quick phrases use shorter forms without estar, especially for menus or notices.
Banheiro cheio — a quick note sometimes seen near facilities meaning currently occupied or crowded
Estacionamento cheio — parking lot full
Assento vazio — empty seat
Garrafas vazias — empty bottles (label or recycling bin)
Using cheio and vazio with prepositions
When you want to specify what something is full or empty of, use de after the adjective.
Examples:
A caixa está cheia de brinquedos.
O copo está vazio de água.
O saco está cheio de roupas.
A geladeira está vazia de comida.
Alternative structure: cheio/ vazio + de + infinitive
You can describe someone being full of a feeling or empty of energy using figurative language with de + noun or de + infinitive idea.
Ele está cheio de energia.
Ela está vazia hoje — used to say she feels drained (no de needed when referring to state of being empty emotionally, but de + noun is common).

Common mistakes and how to avoid them
Mistake 1: forgetting gender agreement. Beginners often say o caixa está cheio when referring to a feminine noun like a caixa. Correct: a caixa está cheia.
Mistake 2: using estar vs ser. Use estar for temporary states: O copo está vazio. Ser would imply a permanent characteristic, which is rare with these adjectives.
Mistake 3: omitting de when specifying the content. Incorrect: A caixa está cheia brinquedos. Correct: A caixa está cheia de brinquedos.
Tips to remember agreement and usage
Tip 1: Identify the noun gender first. If the noun has a instead of o, use the feminine form.
Tip 2: For plural items, add s to the adjective: as cadeiras estão vazias.
Tip 3: Use estar for temporary conditions and for physical states, not ser.
