=Indefinite Syllables= are capable of almost indefinite prolongation; they are those which terminate in a tonic, or any subtonic except one of the three abrupt subtonics, _b_, _d_, _g_; for example, _awe_, _fudge_, _hail_, _arm_. NOTE.--It must be remembered that when for the sake of exercise or effect syllables are extended in time, they must be so uttered that their identity is not impaired,--that is, their enunciation must be free from mouthing. As has been remarked before our pronunciation of vowels is notoriously careless; but by a little attention anyone can easily free himself from this reproach. Frequent practice in the accurate enunciation of the tonic elements as given above, and a habit of watchfulness established as to the orthoepy of those which are most easily obscured, in all words in which they occur, will soon secure, if not a resonant, sonorous utterance with respect to the tonic elements, at least a correct pronunciation. But the correct and distinct pronunciation of the subtonic, and especially of the atonic, elements, when they occur, as is so frequent in English words, in combination, is not so easily accomplished; and orthoepy, in this respect, as a _habit_, cannot be secured without great care and incessant practice. For example, the word _months_ is habitually pronounced by almost everyone as if it were spelled _munce_. The following list for practice will afford material to begin with; other lists should be prepared by the teacher. _Plinth, blithe, sphere, shriek, quote, whether, tipt, depth, robed, hoofed, calved, width, hundredth, exhaust, whizzed, hushed, ached, wagged, etched, pledged, asked, dreamt, alms, adapts, depths, lefts, heav'ns, meddl'd, beasts, wasps, hosts, exhausts, gasped, desks, selects, facts, hints, healths, tenths, salts, builds, wilds, milked, mulcts, elms, prob'd'st, think'st, hold'st, attempt'st, want'st, heard'st, mask'st._ EXERCISE.--Utter the words in the above list in distinct articulate whispers; then with vocality, softly and gently. Avoid hissing and mouthing.
