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

No

While the spelling and fundamental meaning of "bonita" (beautiful/pretty) are the same in both dialects, there are differences in pronunciation and typical usage:

• Pronunciation: In Brazilian Portuguese, the vowels are generally more open (the "o" is pronounced more like "aw"), whereas in Continental Portuguese, the vowels are more closed and the rhythm is more stress-timed.
• Usage: In Brazil, "bonita" is a versatile word used to describe anything from "pretty" and "cute" to "beautiful" or even "noble" (when referring to an idea or gesture). In Portugal, "bonita" is typically reserved for something truly "beautiful" or "grand." For things that are simply "pretty," "cute," or "nice," a Portuguese person would more naturally use the word giro or gira.
