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

Yes

The word "acordo" is identical in both Brazilian and Continental Portuguese in terms of spelling, grammar, and fundamental meaning. It functions both as a noun (meaning "agreement," "deal," or "settlement") and as the first-person singular present indicative of the verb acordar ("I wake up" or "I agree"). The only difference is pronunciation. In Brazilian Portuguese, the vowels are generally more open and the unstressed "o" at the end of the word is pronounced as a clear /u/ sound. In Continental Portuguese, the rhythm is more stress-timed, leading to significant vowel reduction; the unstressed "o" is much shorter and more muffled, and the "a" may sound more closed.
