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

No

The word "come" is not the same in typical usage and pronunciation:

• Pronunciation: In Brazilian Portuguese, the vowels are more open and the final "e" is clearly articulated (pronounced roughly as KOH-mee). In Continental Portuguese, the vowels are more closed and the final "e" is often reduced or nearly silent (pronounced roughly as KÕM).
• Usage (Social Address): In Brazil, the form "come" is the standard way to address someone informally using the pronoun você. In Portugal, "come" is used for formal address, while the informal "you" requires the conjugation comes (using the pronoun tu).
• Usage (Slang): In Brazil, "comer" is frequently used in slang to mean being deceived or tricked (e.g., "comer um golpe"), whereas in Portugal, the expression "ser enganado" is more standard.
