⟩. Around 1300, letter case was increasingly distinguished, with upper- and lower-case B taking separate meanings. Following the advent of printing in the 15th century, Holy Roman Empire (Germany) and Scandinavia continued to use forms of blackletter (particularly Fraktur), while England eventually adopted the humanist and antiqua scripts developed in Renaissance Italy from a combination of Roman inscriptions and Carolingian texts. The present forms of the English cursive B were developed by the 17th century.
⟩ meaning "house".[5][a] The Hebrew letter bet⟨ב⟩ is a separate development of the Phoenician letter.[3]
By Byzantine times, the Greek letter ⟨Β⟩ came to be pronounced /v/,[3] so that it is known in modern Greek as víta (still written βήτα). The Cyrillic letter ve⟨В⟩ represents the same sound, so a modified form known as be⟨Б⟩ was developed to represent the Slavic languages' /b/.[3] (Modern Greek continues to lack a letter for the voiced bilabial plosive and transliterates such sounds from other languages using the digraph/consonant cluster⟨μπ⟩, mp.)
Use in writing systems
English
In English, ⟨b⟩ denotes the voiced bilabial stop/b/, as in bib. In English, it is sometimes silent. This occurs particularly in words ending in ⟨mb⟩, such as lamb and bomb, some of which originally had a /b/ sound, while some had the letter ⟨b⟩ added by analogy (see Phonological history of English consonant clusters). The ⟨b⟩ in debt, doubt, subtle, and related words was added in the 16th century as an etymological spelling, intended to make the words more like their Latin originals (debitum, dubito, subtilis).

As /b/ is one of the sounds subject to Grimm's Law, words which have ⟨b⟩ in English and other Germanic languages may find their cognates in other Indo-European languages appearing with ⟨bh⟩, ⟨p⟩, ⟨f⟩ or ⟨φ⟩ instead.[3] For example, compare the various cognates of the word brother. It is the seventh least frequently used letter in the English language (after V, K, J, X, Q, and Z), with a frequency of about 1.5% in words.
Other languages
Many other languages besides English use ⟨b⟩ to represent a voiced bilabial stop.
In the International Phonetic Alphabet, [b] is used to represent the voiced bilabial stopphone. In phonological transcription systems for specific languages, /b/ may be used to represent a lenisphoneme, not necessarily voiced, that contrasts with fortis /p/ (which may have greater aspiration, tenseness or duration).
B is also a musical note. In English-speaking countries, it represents Si, the 12th note of a chromatic scale built on C. In Central Europe and Scandinavia, "B" is used to denote B-flat and the 12th note of the chromatic scale is denoted "H". Archaic forms of 'b', the b quadratum (square b, ♮) and b rotundum (round b, ♭) are used in musical notation as the symbols for natural and flat, respectively.
In Contracted (grade 2) English braille, 'b' stands for "but" when in isolation.
In computer science, B is the symbol for byte, a unit of information storage.
In engineering, B is the symbol for bel, a unit of level.
The blood-type B emoji (🅱️) was added in Unicode 6.0 in 2010, and became a popular internet meme in 2018 where letters would be replaced with the emoji.[6]
