Master

23. a. In early use (my) young master, little master, occur as designations applied by servants and inferiors generally to the boys and young men of the families of their superiors. App. as a development from this mode of expression, the word master (after the phonetic separation of Mr.) came to be the usual prefix to the name of a young gentleman not considered old enough to be entitled to be called ‘Mr.’. Hence occas. masters and misses = young people. Also †master-miss: an effeminate youth.
