Editing Circumflex (section)

==== Stress ====
[[File:27 Y Parêd.jpg|thumb|Bilingual sign showing the use of the circumflex in Welsh as an indicator of length and stress: ''parêd'' [paˈreːd] "parade", as opposed to ''pared'' [ˈparɛd] "partition wall".]]

The circumflex accent marks the [[Stress (linguistics)|stressed vowel]] of a word in some languages:

* [[Portuguese language|Portuguese]] ''â'', ''ê'', and ''ô'' are stressed [[close vowels]], opposed to their open counterparts ''á'', ''é'', and ''ó'' (see below).
* [[Welsh language|Welsh]]: the circumflex, due to its function as a disambiguating lengthening sign (see above), is used in polysyllabic words with word-final long vowels. The circumflex thus indicates the stressed syllable (which would normally be on the [[penult|penultimate syllable]]), since in Welsh, non-stressed vowels may not normally be long. This happens notably where the singular ends in an ''a'',  to, e.g. singular ''camera'', ''drama'', ''opera'', ''sinema'' → plural ''camerâu'', ''dramâu'', ''operâu'', ''sinemâu''; however, it also occurs in singular nominal forms, e.g. ''arwyddocâd''; in verbal forms, e.g. ''deffrônt'', ''cryffânt''; etc.
