B

B or b is the second letter of the Latin-script alphabet.  It represents the voiced bilabial stop in many languages, including English. In some other languages, it is used to represent other bilabial consonants.

The letter B was part of the Phoenician alphabet more than 3000 years ago in 1000 BCE. At that time, the letter was called beth and looked a little different, but it made the sound of b and was second in the alphabet.
