Stress and final glottal stop
Stress is a distinctive feature in Tagalog. Primary stress occurs on either the final or the penultimate syllable of a word. Vowel lengthening accompanies primary or secondary stress except when stress occurs at the end of a word.Tagalog words are often distinguished from one another by the position of the stress and/or the presence of a final glottal stop. In formal or academic settings, stress placement and the glottal stop are indicated by a diacritic above the final vowel. The penultimate primary stress position is the default stress type and so is left unwritten except in dictionaries. The name of each stress type has its corresponding diacritic in the final vowel.
