I must however remark that most, if not all syllables, derived from some important word, have some degree of accent:[44] So that in compounds, there are usually as many accents as radicals. Thus in _sanctify_, which is composed of two radicals, _sanctus_ and _fio_, we observe two accents; the strongest on the first syllable. The same may be observed in _magnanimity_, from _magnus_ and _animus_, in _promogeniture_, &c. except that in these the principal accent is on the third syllable. Notwithstanding it is a general rule, that there are as many accents in a word, as radicals, yet one of them at least is frequently removed from the principal syllable, by the analogy of termination, which prevails over all other reasons. Thus in _mathematics_, the two accents lie on the proper syllables; but in _mathematician_, the last accent is removed to a less important place. In _imperceptible_, the principal accent, with propriety, lies on the third syllable, which being derived from a verb (_capio_) is the most important. The particle _im_, being the privative, or that syllable which changes the meaning of the whole word from affirmative to negative, becomes important and has some degree of accent. But in the derivative _imperceptibility_, while the first and third syllables retain an accent, the analogy of termination carries the principal accent to the fifth syllable, which is adventitious and less important than the others.[45] In many compounds, as, _earth-quake_, _rain-bow_, each syllable is pronounced with the stress that belongs to accented syllables; and there is little or no distinction of accent. The reason is obvious: There is no difference in the importance of the syllables; both are equally necessary to convey the idea. By giving one syllable the whole accent, such a word loses its original meaning, or at least its force, as may be observed in the word _hussy_, a corruption of _house-wife_; which, from an affectation of a unity of accent, and a hasty pronunciation, has sunk into a low word. From the same ridiculous affectation, _work-house_ is, by some people, pronounced _work-us_. On this head, I shall only observe further, that some words of many syllables have three accents; of which we have an example in _val'etu'dina'rian_. It has been already remarked that the composition of words, and the ease of speaking, require a plurality of accent. The reason why words of many syllables have two or three accents, is plain to any man that attempts to pronounce them without an accent.
