B (named bee /ˈbiː/)^[1] is the second letter in the ISO basic Latin alphabet. It is used to represent a variety of bilabial sounds (depending on language), most commonly a voiced bilabial plosive.

History [link]

⟨B⟩ may have started as a pictogram of the floorplan of a house in Egyptian hieroglyphs. By 1050 BC, the Phoenician alphabet's letter had a linear form that served as the beth.

Typography [link]

The modern lowercase ⟨b⟩ derives from later Roman times, when scribes began omitting the upper loop of the capital.

Use [link]

In English, most other languages that use the Latin alphabet, and the International Phonetic Alphabet, ⟨b⟩ denotes the voiced bilabial plosive /b/, as in bib. In English it is sometimes silent; most instances are derived from old monosyllablic words with the b final and immediately preceded by an m, such as lamb and bomb; a few are examples of etymological spelling to make the word more like its Latin original, such as debt or doubt.

In Estonian, Icelandic, and Chinese pinyin, ⟨b⟩ does not denote a voiced consonant; instead, it represents a voiceless /p/ that contrasts with either a geminated /pp/ (in Estonian) or an aspirated /pʰ/ (in Chinese, Danish and Icelandic), represented by ⟨p⟩. In Fijian ⟨b⟩ represents a prenasalized /mb/, whereas in Zulu and Xhosa it represents an implosive /ɓ/, in contrast to the digraph ⟨bh⟩ which represents /b/.

Finnish only uses ⟨b⟩ in loanwords.

⟨B⟩ is also a musical note. Its value varies depending on the region; a ⟨b⟩ in Anglophone countries represents a note that is a semitone higher than the B note in Northern Continental Europe. (Anglophone B is represented in Northern Europe with ⟨H⟩.) Archaic forms of ⟨b⟩, the b quadratum (square b, ♮) and b rotundum (round b, ♭) remain in use for musical notation as the symbols for natural and flat, respectively.

In Contracted (grade 2) English braille, ⟨b⟩ stands for "but" when in isolation.
