B

B or b (pronounced /ˈbiː/, bee) is the second letter in the ISO basic Latin alphabet. It represents the voiced bilabial stop in many languages, including English. In some other languages, it is used to represent other bilabial consonants.

Old English was originally written in runes, whose equivalent letter was beorc ⟨ᛒ⟩, meaning "birch". Beorc dates to at least the 2nd-century Elder Futhark, which is now thought to have derived from the Old Italic alphabets' ⟨ Wikipedia
