Etymology 1

Old English letter B, from 7th century replacement by Latin B of the Anglo-Saxon Futhorc letter ᛒ (B, “beorc”).

Letter

B uppercase (lowercase b)

1. The second letter of the English alphabet, called bee and written in the Latin script.

Usage notes

In Modern English, the letter B is sometimes silent, e.g. in climb, and debt.

Apostrophes are sometimes used to form plurals of single upper case letters, especially at the start of a sentence:

A’s are difficult to achieve in this class.

Usually, though, the apostrophe is avoided when there is no risk of confusion:

She gets straight As in school.
