Unleavened; unfermented.
   B () is the second letter of the English alphabet. (See Guide to
   Pronunciation, // 196, 220.) It is etymologically related to p, v, f, w
   and m , letters representing sounds having a close organic affinity to
   its own sound; as in Eng. bursar and purser; Eng. bear and Lat. ferre;
   Eng. silver and Ger. silber; Lat. cubitum and It. gomito; Eng. seven,
   Anglo-Saxon seofon, Ger. sieben, Lat. septem, Gr."epta`, Sanskrit
   saptan. The form of letter B is Roman, from Greek B (Beta), of Semitic
   origin. The small b was formed by gradual change from the capital B.
