Portuguese Phonology - Stress

Stress

Primary stress may fall on any of the three final syllables of a word, but mostly on the last two. There is a partial correlation between the position of the stress and the final vowel; for example, the final syllable is usually stressed when it contains a nasal phoneme, a diphthong, or a close vowel. The orthography of Portuguese takes advantage of this correlation to minimize the number of diacritics.

Because of the phonetic changes that often affect unstressed vowels, pure lexical stress is less common in Portuguese than in related languages, but there is still a significant number of examples of it:

dúvida /ˈduvidɐ/ "doubt" (noun) vs. duvida /duˈvidɐ/ "he doubts"
ruiram /ʁuˈiɾɐ̃ũ/ "they collapsed" vs. ruirão /ʁuiˈɾɐ̃ũ/ "they will collapse"
falaram /faˈlaɾɐ̃ũ/ "they spoke" vs. falarão /falaˈɾɐ̃ũ/ "they will speak" (Brazilian pronunciation)
ouve /ˈovi/ "he hears" vs. ouvi /oˈvi/ "I heard" (Brazilian pronunciation)
túnel /ˈtunɛl/ "tunnel" vs. tonel /tuˈnɛl/ "wine cask" (European pronunciation)

Famous quotes containing the word stress:

    Like all weak men he laid an exaggerated stress on not changing one’s mind.
    W. Somerset Maugham (1874–1966)

    While ... we cannot and must not hide our concern for grave world dangers, and while, at the same time, we cannot build walls around ourselves and hide our heads in the sand, we must go forward with all our strength to stress and to strive for international peace. In this effort America must and will protect herself.
    Franklin D. Roosevelt (1882–1945)

    Anyone who wishes to combine domestic responsibilities and paid employment with the least stress and most enjoyment might start by pondering this paradox: the first step to better functioning is to stop blaming herself for not functioning well enough.
    Faye J. Crosby (20th century)
