THE QUANTITY OF SYLLABLES.

The quantity of a syllable is the space of time taken up in pronouncing it. That part of grammar which treats of the quantity and accent of Syllables, and of the measures of verse, is called PROSODY.

Syllables, with respect to their quantity, are either long or short.

A long syllable in pronouncing requires double the time of a short; as, tĕndĕrě. Some syllables are common; that is, sometimes long, and sometimes short; as the second syllable in volucris.

A vowel is said to be long or short by nature, which is always so by custom, or by the use of the poets.

In polysyllables or long words, the last syllable except one is called the Penultima, or, by contraction, the Penult; and the last syllable except two, the Antepenultima.

When the quantity of a syllable is not fixed by some particular rule, it is said to be long or short by authority; that is, according to the usage of the poets. Thus le in lego is said to be short by authority, because it is always made short by the Latin poets. In most Latin words of one or two syllables, according to our manner of pronouncing, we can hardly distinguish by the ear a long syllable from a short. Thus le in lego and legi seem to be sounded equally long; but when we pronounce them in composition, the difference is obvious; thus, perlego, perlēgi; relego, -ère; relego, -āre, &c. The rules of quantity are either General or Special. The former apply to all syllables, the latter only to some certain syllables.

GENERAL RULES.

I. A vowel before another vowel is short; as,

Měus alius: so nihil; h in verse being considered only as a breathing. In like manner in English, create, běhave.

Exc. 1. I is long in fio, fiebam, &c. unless when followed by r; as, fïèri, fiĕrem; thus,

Omnia jam fient, fieri quæ posse negabam. Ovid.

Exc. 2. E having an i before and after it, in the fifth declension, is long; as, speciei. So is the first syllable in der, dius, eheu, and the penultima in aulai, terrai, &c. in Pompei, Cai, and such like words; but we sometimes find Pompei in two syllables, Horat. Od. II. 7.

Exc. 3. The first syllable in ohe and Diana is common; so likewise is the penult of genitives in ius; as, illius, unius, &c. to be read long in prose. Alius, in the genitive is always long, as being contracted for aliius; alterius, short.

In Greek words, when a vowel comes before another, no certain rule concerning its quantity can be given.

Sometimes it is short: as, Danăãe, Iděa, Sophĩa, Symphonĩa, Simõis, Hỹades, Phǎon, Deucalion, Pygmalion, Thebais, &c.

Often it is long: as, Lycaon, Machaon, Didymãon; Amphion, Arion, Ixion, Pandion; Nâis, Lais, Achata; Briseis, Cadmeis; Latous; & Latõis, Myrtõus, Nerētus, Priamētus; Achelōtus, Minōïus; Archelaus, Menelāus, Amphiarāus, Æneas, Penēus, Epēus, Acrisionēus, Adamantēus, Phœbēus, Gi ganteus; Darius, Basirius, Eugenius, Bacchius; Cassiopea, Cæsarea, Chæronea, Cytherea, Galėtea, Laodicea, Medea, Panthea, Penelopea; Clio, Enyo, Elegia, Iphigenia, Alexandria, Thalia, Antiochia, idololatria, litania, politia, &c. Laertes, Derphöbus, Dērjanira, Trões, herões, &c.

Sometimes it is common: as, Chorea, platea, Malea, Nereïdes, canopeum, Orion, Geryon, Eos, Eous, &c. So in foreign words, Michael, Israel, Raphael, Abraham, &c.

The accusative of nouns in eus is usually short; as, Orphea, Salmonea, Capharĕa, &c. but sometimes long; as, Idomenea, Ilionēa, Virg. Instead of Elegia, Cytherea, we find Elegera, Cythereia, Ovid. But the quantity of Greek words cannot be properly understood without the knowledge of Greek. In English, a vowel before another is also sometimes lengthened; as, science, idēa.

II. A vowel before two consonants, or before a double consonant, is long; (by position, as it is called ;) as,

ārma, fällo, axis, gāza, mājor: the compounds of jugum excepted; as, bijūgus, quadrijŭgus, &c.

When the foregoing word ends in a short vowel, and the following begins with two consonants or a double one, that vowel is sometimes lengthened by the position; as,

But this rarely occurs.

Ferte cili flammas, date velă, scandite muros. Virg.

¶ A vowel before a mute and a liquid is common; as in the middle syllable in volucris, tenebræ, thus,

Et primò similis volŭcri, mox vera volūcris. Ovid.
Nox tenebras, profert, Phœbus fugat inde tenebras. Id.

But in prose these words are pronounced short. So peragro, pharetra, podagra, chiragra, celebris, latebræ, &c.

To make this rule hold, three things are requisite. The vowel must be naturally short, the mute must go before the liquid, and be in the same syllable with it. Thus a in patris is made common in verse, because a in pater is naturally short, or always so by custom; but a in matris acris is always long, because long by nature or custom in mater and acer. In like manner the penult in `salūbris, ambŭlācrum, is always long, because they are derived from salus, salūtis, and ambulātum. So a in arte, abluo, &c. is long by position, because the mute and the liquid are in different syllables. L and r only are considered as liquids in Latin words; m and n do not take place except in Greek words.

III. A contracted syllable is long; as,

Nil, for nihil; mi, for mihi; cōgo, for coago; alius, for aliius; tibicen, for tibiicen; it, for iit; sōdes, for si audes; nōlo, for non volo; bīgæ, for bijugæ; scilicet, for scire licet, &c.

IV. A diphthong is always long; as,

Aurum, Cæsar, Eubœ, &c. Only præ in composition before a vowel is commonly short; as, præire, præustus; thus,

Nec totâ tamen ille prior præcunte carinâ. Virg.
Stipitibus durus agitur sudibusque præustis. Id.

But it is sometimes lengthened; as,

-cum vacuus domino præiret Arion. Statius.

In English we pronounce several of the diphthongs short, by sinking the sound of one vowel; but then there is properly no diphthong.

SPECIAL RULES.

I. CONCERNING THE FIRST AND MIDDLE SYLLABLES.

Preterites and Supines of Two Syllables.

V. Preterites of two syllables lengthen the former syllable; as, Vēni, vidi,

vici.

Except bibi, scidi from scindo, fidi from findo, tuli, dědi, and stěti, which are shortened.

VI. Supines of two syllables lengthen the former syllable; as, Visum, cāsum, mōtum.

Except sătum, from sĕro; citum, from cieo; litum, from lino; situm, from sino; stătum, from sisto; štum, from eo; dătum, fsom do; rutum, from the compounds of ruo; quitum, from queo; rătus, from reor.

Preterites which double the first syllable.

VII. Preterites which double the first syllable have both the first syllables short; as,

Cěcidi, tětigi, pěpůli, pěpěri, didici, tutudi: except cecidi, from cado; pěpēdi, from pēdo; and when two consonants intervene; as, fěfelli, tětendi, &c.

INCREASE OF NOUNS.

A noun is said to increase when it has more syllables in any of the oblique cases than in the nominative; as, rex, rēgis. Here re is called the encrease or crement, and so through all the other cases. The last syllable is never esteemed a crement.

Some nouns have a double increase, that is, increase by more syllables than one; as, iter, itīnēris.

A noun in the plural is said to increase, when in any case it has more syllables than the genitive singular; as, gener, genēri, generōrum.

Nouns of the first, fourth, and fifth declensions, do not increase in the singular number, unless where one vowel comes before another; as, fructus, fructŭi; res, rěi ; which fall under Rule I.

Third Declension.

VIII. Nouns of the third declension which increase, make a and o long; e, i, and u short; as,

Pietātis, honōris; mulieris, lapidis, murmuris.

The chief exceptions from this rule are marked under the formation of the genitive in the third declension. But here perhaps it may, be proper to be more particular.

A.

A noun in A shortens atis in the genitive; as, dogma, -ălis; poema, -ătis.

0.

O shortens inis, but lengthens ēnis and ōnis; as, Cardo, inis; Virgo, inis; Anio, ēnis; Cicero, -ōnis. Gentile or patrial nouns vary their quantity. Most of them shorten the genitive; as, Macedo, -õnis; Saxo, -õnis. Some are long; as, Suessiones, Vettones. Brittones is common.

INCREASE OF VERBS.

A verb is said to increase, when any part has more syllables than the second person singular of the present of the indicative active; as, amas, amāmus, where the second syllable ma is the increase or crement; for the last syllable is never called by that

name.

A verb often increases by several syllables; as, amas, amābāmĭni; in which case it is said to have a first, second, or third increase.

X. In the increase of verbs, a, e, and o, are long; and u, short; as,
Amare, docere, amātōte; legimus, sumus, volumus.

The poets sometimes shorten děděrunt and stětěrunt; and lengthen rimus and ritis, in the future of the subjunctive; as, transieritis aquas, Ovid. All the other exceptions from this rule are marked in the formation of the verb.

The first or middle syllables of words which do not come under any of the foregoing rules, are said to be long or short by authority; and their quantity can only be discovered from the usage of the poets, which is the most certain of all rules.

REMARKS ON THE QUANTITY OF THE PENULT OF WORDS.

1. Patronymies in IDES or ADES usually shorten the penult; as, Priamides, Atlantiădes, &c. Unless they come from nouns in eus; as, Pelides, Tydides, &c.
