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

No

The primary difference lies in typical usage and semantic scope. In Brazil, machucar is a versatile, universal verb used for both physical injuries (scratches, bruises, cuts) and emotional pain (hurting someone's feelings). In Portugal, while machucar is understood, it is less common as the primary verb for physical injuries; instead, Portuguese speakers prefer ferir (to injure) or describing the specific type of injury (e.g., ficar com um arranhão — to get a scratch). Crucially, for emotional distress, a Portuguese person would almost exclusively use magoar, whereas a Brazilian would naturally use machucar. Additionally, the pronunciation in Brazil is more open and vocalic, while in Portugal, the vowels are more closed and the rhythm is more staccato.
