How does circumflex change pronunciation?
Indicated by the sign ^, it is placed over a vowel to show that the vowel or syllable containing it must be pronounced in a certain way. In French, the vowel so marked has a certain grave and long sound quality. The circumflex accent adds a certain musicality to a word; some would argue it confers poetry to words.
What is the Ô called?
The circumflex accent marks the stressed vowel of a word in some languages: Portuguese â, ê, and ô are stressed "closed" vowels, opposed to their open counterparts á, é, and ó (see below).
How do you use circumflex?
The “6” key becomes a circumflex accent when shifted, so CTRL+SHIFT+6 plus either “a”, “e”, “i”, “o”, or “u” generates “â”, “ê”, “î”, “ô”, and “û”, respectively. To put a cedilla underneath the letter “c”, use CTRL+comma before typing “c” or “C” to get “ç” or “Ç”.
