Sinto aversão por

You follow the phrase with a noun or a verb. If it is a noun, remember to match the gender. For example, Sinto aversão por mentiras (I feel aversion to lies). You can use it to describe physical smells or abstract concepts. It sounds more sophisticated than just saying não gosto (I don't like). It adds weight to your opinion. Use it when you want to be taken seriously.

Use this when you want to express a firm stance. It works well in deep conversations with friends. It is perfect for discussing ethics or personal values. You can use it at a dinner table if someone offers you something truly repulsive. It is great for setting boundaries in a professional setting. Use it when a simple 'no' isn't enough to convey your disgust.

Do not use this for minor inconveniences. Don't say it if you just missed the bus. It is too heavy for trivial things like a rainy day. Avoid using it in very casual slang-heavy groups. It might sound a bit too dramatic or 'posh' there. Never use it to describe people you just find slightly annoying. It is a 'bridge-burning' kind of phrase if used toward a person.

Portuguese culture values social harmony and politeness. However, being direct about your 'repulsa' (repulsion) is respected when it involves character. The word aversão has roots in Latin, meaning 'turning away.' In Brazil and Portugal, expressing this often comes with a physical gesture. You might see a slight shiver or a hand wave. It shows that your soul and body agree on the dislike.

You might hear Tenho aversão a. This is almost identical in meaning. Some people say Sinto uma certa aversão. Adding uma certa (a certain) softens the blow slightly. In more casual settings, people might just say Isso me dá nojo (That gives me disgust). But Sinto aversão por remains the most elegant way to be hater.
