✦Grammar Breakdown
Nãoestraguesapropriedade.
Negação (Não)
‘Não’ precede the verb to make a negative command. It works with the subjunctive form of the verb.
Imperativo Negativo
In Portuguese, a negative command uses the present subjunctive (estragues) rather than the affirmative imperative (estraga).
Verbo ‘estragar’
‘Estragar’ means ‘to ruin, to damage, to spoil’. In the negative imperative it becomes ‘estragues’ (2nd‑person singular).
Artigo Definido (a)
The feminine singular article ‘a’ agrees with the noun ‘propriedade’.
Substantivo ‘propriedade’
Means ‘property, belongings, estate’. It is a feminine noun, hence the article ‘a’.

✕Common Mistakes
Não estragar a propriedade.
The infinitive cannot be used in a command. The negative imperative requires the present subjunctive form ‘estragues’.
Não estrague a propriedade.
‘Estrague’ is the 3rd‑person singular subjunctive, used for formal ‘you’ (você) or third‑person commands. For informal ‘tu’, use ‘estragues’.
↔Alternatives

Don't damage the property.
Não cause danos à propriedade.
Don't cause damage to the property.
Cuide da propriedade.
Take care of the property.
Cultural Tip
In Brazil and Portugal, respecting other people's belongings is a sign of good manners. When speaking to strangers or in formal settings, you might add ‘por favor’ after the command: ‘Não estragues a propriedade, por favor.’ In informal contexts among friends, the plain negative imperative is enough.
