Cumpre ressaltar

You use it at the start of a sentence to introduce a fact or observation. It functions as a bridge between your previous thought and a new, important one. In Portuguese, cumpre comes from the verb cumprir (to fulfill/comply). So, you are literally saying it is a duty or a necessity to mention this fact. It’s elegant and makes you sound incredibly articulate.

This is your go-to phrase for professional emails, academic papers, or serious debates. Use it when you want to sound authoritative and organized. It’s perfect for a job interview when you want to highlight a specific skill. You can also use it in a meeting to bring the team back to the main goal. It shows you have a structured mind.

Avoid this phrase when you are grabbing a beer with friends or talking to a toddler. If you say cumpre ressaltar que a pizza está fria to your best friend, they might think you’ve swallowed a dictionary. It’s too stiff for casual hangouts. Also, don't use it for trivial things. If the point isn't actually important, the phrase loses its power. Keep it for the heavy hitters.

Portuguese culture often values formal eloquence, especially in writing. This phrase is a staple of 'Juridiquês' (legal jargon) but has moved into general professional life. It reflects the Latin roots of the language where duty and speech are often linked. It’s a sign of a 'culto' (educated) speaker who respects the structure of an argument.

You might also hear cabe ressaltar or vale destacar. Cabe ressaltar is almost identical in meaning. Vale destacar is slightly softer, more like 'it's worth noting.' If you want to be even more formal, you could say urge salientar. But cumpre ressaltar hits that perfect sweet spot of being sophisticated without being archaic.
