Good illustrations of the parity and disparity of accent may be drawn from certain names of places. Let there be such a sentence as the following: _the lime house near the bridge north of the new port_. Compare the parity of accent on the pairs of words _lime_ and _house_, _bridge_ and _north_, _new_ and _port_, with the disparity of accent in the compound words _Límehouse_, _Brídgenorth_, and _Néwport_. The separate words _beef steak_, where the accent is nearly at _par_, compared with the compound word _sweépstakes_, where there is a great disparity of accent, are further illustrations of the same difference. The difference between a compound word and a pair of words is further illustrated by comparing such terms as the following:--_bláck bírd_, meaning a _bird that is black_, with _bláckbird_ = the Latin _merula_; _blúe béll_, meaning a _bell that is blue_, with _blúebell_, the flower. Expressions like a _shárp edgéd instrument_, meaning _an instrument that is sharp and has edges_, as opposed to _a shárp-edged instrument_, meaning _an instrument with sharp edges_, further exemplify this difference. Subject to a few exceptions, it may be laid down, that, in the English language, _there is no composition unless there is either a change of form or a change of accent_. § 359. The reader is now informed, that unless he has taken an exception to either a statement or an inference, he has either seen beyond what has been already laid down by the author, or else has read him with insufficient attention. This may be shown by drawing a distinction between a compound form and a compound idea.
