Syllable
Definition:
(n.) An elementary sound, or a combination of elementary sounds, uttered together, or with a single effort or impulse of the voice, and constituting a word or a part of a word. In other terms, it is a vowel or a diphtong, either by itself or flanked by one or more consonants, the whole produced by a single impulse or utterance. One of the liquids, l, m, n, may fill the place of a vowel in a syllable. Adjoining syllables in a word or phrase need not to be marked off by a pause, but only by such an abatement and renewal, or reenforcement, of the stress as to give the feeling of separate impulses. See Guide to Pronunciation, /275.
(n.) In writing and printing, a part of a word, separated from the rest, and capable of being pronounced by a single impulse of the voice. It may or may not correspond to a syllable in the spoken language.
(n.) A small part of a sentence or discourse; anything concise or short; a particle.
(v. t.) To pronounce the syllables of; to utter; to articulate.
