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

No

While the meaning of "te" (the second-person singular object pronoun) remains the same—meaning "you" or "to you"—the usage and grammar regarding its placement differ significantly between the two dialects:

• Pronoun Placement (Syntax): Brazilian Portuguese (BP) heavily favors proclisis, which is placing the pronoun before the verb (e.g., "Eu te amo"). Continental Portuguese (EP) follows stricter rules that favor enclisis, placing the pronoun after the verb in affirmative sentences (e.g., "Eu amo-te").
• Grammatical Consistency: In much of Brazil, "te" is used colloquially even when the speaker is addressing someone as "você." Because "você" is grammatically treated as a third-person pronoun, this creates a "mixed" usage where a second-person pronoun ("te") is paired with a third-person subject. In Portugal, "te" is strictly paired with the second-person subject "tu."
