Typewritten text in Portuguese; note the acute accent, tilde, and circumflex accent.. Portuguese orthography is based on the Latin alphabet and makes use of the acute accent, the circumflex accent, the grave accent, the tilde, and the cedilla to denote stress, vowel height, nasalization, and other sound changes.
The word diacritic is a noun, though it is sometimes used in an attributive sense, whereas diacritical is only an adjective. Some diacritics, such as the acute ó , grave ò , and circumflex ô (all shown above an 'o'), are often called accents. Diacritics may appear above or below a letter or in some other position such as within the letter or ...
The orthography of Portuguese takes advantage of this correlation to minimize the number of diacritics, but orthographic rules vary in different regions (e.g., Brazil and Portugal), and should not be used as a reliable guide to stress, despite the existing correlations found in the grapheme-phoneme conversion of Portuguese data.

The grave accent ( ̀) (/ ɡ r eɪ v / GRAYV [1] [2] or / ɡ r ɑː v / GRAHV [1] [2]) is a diacritical mark used to varying degrees in French, Dutch, Portuguese, Italian, Catalan and many other western European languages as well as for a few unusual uses in English.

After the implementation of the Orthographic Agreement, it was abolished altogether from all Portuguese words.
It is, however, unsuitable for use as a diacritic on modern computer systems, as it is a spacing character. Two other spacing circumflex characters in Unicode are the smaller modifier letters U+02C6 ˆ MODIFIER LETTER CIRCUMFLEX ACCENT and U+A788 ꞈ MODIFIER LETTER LOW CIRCUMFLEX ACCENT , mainly used in phonetic notations or as a sample of the ...
