Note. In the Index of this work, when the penult of a word is long, it is marked with the accent; when the penult is short, the antepenult is marked. The reader should however bear in mind that a syllable may be long even though it contain a short vowel, as by Rule I, (2), above.
III. Vowels and Consonants. These rules depend upon those of Syllabication:
(1) A vowel generally has its long English sound when it ends a syllable: He´-ro, I´-o, Ca´-cus, I-tho´-me, E-do´-ni, My-ce´-næ.
(2) A vowel generally has its short English sound in a syllable that ends in a consonant: Hel´-en, Sis´-y-phus, Pol-y-phe´-mus. But e in the termination es has its long sound: Her´mes, A-tri´-des.
(3) The vowel a has an obscure sound when it ends an unaccented syllable: A-chæ´-a; so, also, the vowel i or y, not final, after an accented syllable: Hes-per´-i-des; and sometimes i or y in an unaccented first syllable: Ci-lic´-i-a.
(4) Consonants have their usual English sounds; but c and g are soft before e, i, y, æ, and œ: Ce´-to, Ge´-ry-on, Gy´-ges; ch has the sound of k: Chi´-os; and c, s, and t, immediately preceded by the accent and standing before i followed by another vowel, commonly have the sound of sh: Sic´-y-on (but see Latin grammars and English dictionaries for exceptions).
IV. Syllabication.
(1) The penultimate syllable ends with a vowel: e.g. Pe-ne´-us, I-tho´-me, A´-treus, Hel´-e-nus;
Except when its vowel is followed by x or by two consonants (not a mute with l or r), then the vowel is joined with the succeeding consonant: Nax-os, Cir-ce, Aga-mem-non.
