não primeira vez

You will almost always see this preceded by não é a. The full standard structure is Não é a primeira vez. You can use it to show off your expertise. You can also use it to complain about a recurring problem. It fits perfectly at the start of a sentence to set the stage. It also works as a standalone comment when you roll your eyes at a friend's predictable behavior.

Use it when you arrive at a restaurant you love. Use it when your computer crashes for the third time today. It is great for professional settings to show you have experience. Use it in romantic contexts to talk about shared memories. It is a versatile tool for emphasizing frequency or persistence. If your friend is late again, this is your weapon of choice.

Don't use it if you are actually doing something for the first time. That would be confusing and potentially awkward. Avoid using it in very high-stakes legal documents where specific dates are required. Don't use it to dismiss someone's genuine excitement about a new experience. It can sound a bit cynical if overused. Nobody likes a 'know-it-all' who has seen everything before.

Brazilians and Portuguese people value shared history and 'jeitinho' (finding a way). Saying não é a primeira vez often implies a level of street smarts. It suggests you aren't a 'turista' (tourist) in life. It reflects a culture that values experience over raw theory. It is also a common trope in Brazilian soap operas for dramatic reveals. 'It's not the first time he lied to me!' is a classic line.

You might hear Não é de hoje, which means 'it's not just from today.' Another one is Já perdi a conta, meaning 'I've already lost count.' For a more formal touch, use Não é a primeira ocasião. In slang, you might hear De novo?, which is just a tired 'Again?'. Each variation adds a slightly different flavor to your frustration or expertise.
