Origin & History of “lad”
Lad originally meant ‘male of low status or social rank’, and hence ‘male servant’, but by the 14th century its progression to the present-day ‘young male’ was well under way. It is not known where it came from, but there seems to be a strong likelihood of a Scandinavian origin (Norwegian has -ladd in compounds referring to ‘(male) persons’).
