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

No

While the fundamental meaning of "queimar" (to burn, to scorch, or to consume) is identical in both varieties, there are notable differences in typical usage, grammar, and vocabulary that surround the word.

• Usage (Idioms): In Brazil, "queimar" is frequently used in the idiomatic expression "queimar o filme" to mean ruining one's reputation or image. While a Portuguese person understands the concept, they are more likely to use different verbs like "ficar mal" or "manchar a imagem."
• Grammar (Gerund vs. Preposition): When describing an ongoing action (the sun burning the skin), Brazilians almost exclusively use the gerund (queimando). In Portugal, the standard construction is the preposition "a" followed by the infinitive (a queimar).
• Vocabulary (Contextual): When referring to a light bulb "burning out," Brazilians often use "queimar," whereas in Portugal, the verb "fundir" is more naturally used for electrical components.
• Pronunciation: In Brazil, the vowels are more open and clearly articulated. In Portugal, vowels are often reduced or swallowed, making the word sound much shorter and more "closed" to an untrained ear.
