Bruce
a Norman surname, but etymology from Brix (place in La Manche, Normandy) is now considered doubtful ["Dictionary of English Surnames"]. Its earliest appearance in Britain is in the person of Robert de Bruis, a baron listed in the Domesday Book. His son, a friend of David I, king of Scotland, was granted by him in 1124 the lordship of Annandale, and David's son, Robert, founded the Scottish House of Bruce. As a given name for U.S. males, most popular for boys born c. 1946-1954.
-osis
word-forming element expressing state or condition, in medical terminology denoting "a state of disease," from Latin -osis and directly from Greek -osis, formed from the aorist of verbs ending in -o. It corresponds to Latin -atio.
