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

No

While the core meanings of "ponto" (such as point, period, stitch, or score) are shared between both dialects, there are differences in typical usage and pronunciation.

• Typical Usage: The way "ponto" is used in common phrases varies. In Brazil, the most common usage is "ponto de ônibus" (bus stop), whereas in Portugal, the standard term is "ponto de autocarro." Additionally, in Brazil, one "bater o ponto" (clocks in/out), while in Portugal, it is more common to "registar o ponto."
• Pronunciation: The nasal vowel "on" is pronounced with a more open and distinct nasal quality in Brazilian Portuguese, whereas in Continental Portuguese, it is typically more closed and often reduced.
