Ter dois pesos e duas medidas.

The origin of this idiom is quite literal and deeply rooted in history. Think about ancient markets and trade. Merchants would often use scales to weigh goods like grains, spices, or precious metals. To cheat customers or gain an unfair advantage, a dishonest merchant might use two different sets of weights. One set would be accurate, used when selling to a trusted buyer. The other set would be slightly lighter, used when selling to an unsuspecting customer. This practice of using 'two weights' (or dois pesos) and consequently, two different standards of measurement (duas medidas), became a symbol of deceit and unfairness. Over time, this literal practice evolved into a figurative expression for any situation where different standards are applied unfairly. It’s a classic case of a concrete, observable action becoming a metaphor for abstract injustice. It’s a very old concept, likely as old as trade itself!

You use ter dois pesos e duas medidas when you notice someone is being unfair. It’s a way to criticize their behavior directly or indirectly. You can use it to describe a person’s general attitude or a specific instance of unfairness. Think about a boss who expects overtime from you but never from their favorite employee. That’s a perfect time to think, 'Ah, they have double standards.' You can say it about individuals, companies, or even governments. It’s a versatile phrase for calling out hypocrisy. Just remember, it’s usually a criticism, so the tone matters. You’re not usually saying this in a congratulatory way! It’s more of an accusation, albeit a common and understood one.

• Your friend complains about loud music from neighbors but blasts their own music late at night. You might think, 'My friend tem dois pesos e duas medidas.'

Use this phrase when you observe clear hypocrisy or inconsistency in how someone applies rules, judgments, or expectations. It’s great for discussions about fairness, ethics, or social justice. You can use it when talking about family dynamics, workplace issues, or even broader societal problems. If you see someone being treated differently for the same action, this phrase fits perfectly. It’s also useful when you want to express your frustration with unfair systems. Think about situations where rules seem to bend for some people but not for others. That’s your cue to use ter dois pesos e duas medidas.

Avoid using this phrase if the situation is merely a misunderstanding or a genuine difference in opinion. It’s not for situations where someone simply has different priorities or preferences. Don't use it if the 'standards' are actually different due to legitimate reasons (e.g., different job roles requiring different responsibilities). It’s also not appropriate for lighthearted teasing unless the context is very clear and the relationship is strong. Using it in a formal setting without strong evidence could make you seem overly critical or accusatory. If you're unsure if it's true hypocrisy, maybe stick to simpler terms like 'unfair' (injusto). It’s not a phrase for casual compliments, obviously! Nobody wants to hear 'You have double standards!' as a compliment.

Many learners might try to translate it too literally or use it in situations that aren't about fairness.
