B/V shifts or mergers are very common, notably in many Spanish variants they will, for example, write “vaca”, betraying the latin root “vacca”, but very clearly say “baca”. Coming from a language that clearly differentates between these sounds, it’s surprising how close they are.

For me the most clear example (in English and other languages that borrowed from Latin) is "to move" and "mobile".
