Secondary Accent. (34)
In words of more than two syllables, there is often a second accent given, but more slight than the principal one, and this is called the secondary accent; as, em”igra’tion, rep”artee’, where the principal accent is marked (‘), and the secondary, (“); so, also, this accent is obvious, in nav”iga’tion, com”prehen’sion, plau”sibil’ity, etc. The whole subject, however, properly belongs to dictionaries and spelling books.
