Latin

There is a similar rule for a Latin word, the penultimate rule:

With few exceptions, Latin words are stressed on the penult (second-to-last syllable) if it is "heavy" (having a long vowel or diphthong or ending in a consonant), and on the antepenult (third-to-last syllable) if the penult is "light" (ending with a short vowel).

Examples:

1. Condĭtum "founded" = co•n—di—tum (heavy, light, final) = cónditum
2. Condītum "seasoned" = co•n—di•i—tum (heavy, heavy, final) = condítum
3. Conductum "brought together" = co•n—du•c—tum (heavy, heavy, final) =condúctum

(— marks a syllable boundary, • marks a mora boundary)

Moraic analysis of Latin

If one counts all "light" syllables as one mora and all "heavy" syllables as two morae, it becomes clear that the accent is essentially always placed three morae before the end of the word. Note, however, that for this analysis to work, one must always count the final syllable as one mora, regardless of its actual syllabic composition.

Examples:

1. In condĭtum the third mora from the end is the n of the first syllable, so the accent falls on cón-
2. In condītum the third mora from the end is the first part of the ī in the second syllable, so the accent falls on dí-
3. In conductum the third mora from the end is the du of the second syllable, so the accent falls on duc-

A somewhat different, and possibly more accurate, analysis is to consider the final syllable as extra metric; then the accent always falls on the syllable with the penult metric mora, and there is no need to define a special type of mora counting for the last syllable.

Other languages

Many other languages have similar but not identical rules for the placement of the accent:
