ACCENT.
This mark (´) is set over a vowel to point out that a particular stress of the voice must be laid on it. When the word has no mark on any of its letters, the penultimate, or last syllable but one, must be pronounced with particular emphasis.
Amo, este, ira, oso,Amó,esté,irá,osó.
Nouns ending in a consonant (plurals excepted) have the last syllable long, and consequently do not require the mark: otherwise, they have it on the syllable on which the stress of the voice lies; as,
Caridad,animal,capitan,favor,interes. | Césped, fácil, órden, carácter, ménos.
