Is the word namorado the same in Brazilian and European Portuguese?

No

While the literal definition of "namorado" is the same in both dialects, there are differences in typical usage, grammar, and pronunciation.

• Typical Usage: In Brazil, "namorado" is the standard term for a boyfriend throughout the duration of a romantic relationship. In Portugal, "namorado" is primarily used for the "dating" or courtship stage. Once a relationship becomes stable, long-term, or involves living together, a Portuguese person is much more likely to use the word companheiro (partner) to express the same idea of a romantic partner.
• Grammar and Syntax: Portuguese (PT-PT) tends to use more definite articles with possessives (e.g., o meu instead of just meu) and different prepositional structures (e.g., à instead of para a). Additionally, PT-PT frequently uses the second-person singular (tu) in informal speech, whereas BR-PT uses você.
• Pronunciation: In most of Brazil, the "d" is palatalized, sounding like "dj" (e.g., namoradojo). In Portugal, the "d" is dental and much more subtle.
