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

Yes

The word "limpamos" is identical in meaning, grammar, spelling, and usage in both Brazilian and Continental Portuguese. It is the first-person plural form of the verb limpar (to clean) in both the Present Indicative and the Preterite Indicative. The only differences are phonetic:

• Vowel Openness: Brazilian Portuguese tends to have more "open" and clearly articulated vowels. In Continental Portuguese, unstressed vowels are often more "closed" or reduced.
• Rhythm: Brazilian Portuguese is generally more syllable-timed (each syllable gets more equal weight), creating a more melodic cadence. Continental Portuguese is more stress-timed, which can make the word sound more "clipped" or rapid due to the reduction of unstressed syllables.
• Sibilants: Depending on the region in Brazil (such as Rio de Janeiro), the "s" might be pronounced as "sh," whereas in many parts of Portugal, the "s" is also pronounced as "sh" (chiado) in certain positions, but the overall prosody of the word will differ.
