Abstract:

Many terms and constructions frowned on a generation ago have been admitted, like many new words, into mainstream parlance and have gained wider acceptance than before. An example is tycoon, in the sense of a wealthy businessman, labeled 'informal' in the first edition of AHD but accepted in the third. Another example is balding, called 'entirely vulgar' in a usage note by panelist Katherine Anne Porter in the first edition but entered without stigma in the third.
