Ê

Ê is not considered a separate letter in Afrikaans but a variation of "E". The circumflex changes the pronunciation of "e" to be /ɛː/ (or /æː/ if the succeeding consonant is either a dorsal or a liquid)

In the Pinyin romanization of Standard Mandarin Chinese, ê represents /ɛ/. It corresponds to Zhuyin ㄝ. The circumflex occurs only if ê is the only letter in the syllable: ề /ɛ̂/ (诶; 誒; "eh!"). Without the circumflex, e as, the only letter in the syllable, represents /ɤ/: è /ɤ̂/ (饿; 餓; "hungry"). Elsewhere, /ɛ/ is written as a (before n) or e (at the end of a syllable), with the appropriate tone mark,: xiān /ɕi̯ɛ́n/ (先; "first"), xuǎn /ɕy̯ɛ̀n/ (选; 選; "to choose"), xué /ɕy̯ɛ̌ ~ ɕy̯ě/ (学; 學; "to learn"), xièxie /ɕi̯ɛ̂.ɕi̯ɛ ~ ɕi̯ê.ɕi̯e/ (谢谢; 謝謝; "thanks").

In Pe̍h-ōe-jī, ê is the fifth tone of e: ê (的; possessive, adjectival suffix).

Diacritics are not considered to be distinct letters of the French alphabet. In French, ê usually changes the pronunciation of e from /ə/ to /ɛ/. It is used instead of "è" for words that used to be written "es".

Ê represents /eː/ and /ɛː/.

Ê is used in UNGEGN romanization system for Khmer to represent /ae/ and /ɛː/, for example Khmêr (ខ្មែរ [kʰmae]) and Dângrêk Mountains (ដងរែក [ɗɑːŋrɛːk]).

Ê is the 7th letter of the Kurdish Kurmanji alphabet and represents /eː/.

In Nynorsk, ê is used to represent the reduction of the Old Norse sequence <eð>, similar to the use of ê for the historical sequence <es> in French. It is mostly used to differentiate words which otherwise would be spelled the same, e.g. vêr 'weather' and ver, imperative of 'to be'.[1]

Ê is used in the Persian Latin (Rumi) alphabet, equivalent to ع.

In Portuguese, ê marks a stressed /e/ only in words whose stressed syllable is in an otherwise unpredictable location in the word: "pêssego" (peach). The letter, pronounced /e/, can also contrast with é, pronounced /ɛ/, as in pé (foot).

Ê is used in Tibetan pinyin to represent /e/, for example Gêrzê County.

Ê is used in the ISO 9:1995 system of Ukrainian transliteration as the letter Є.

Ê is the 9th letter of the Vietnamese alphabet and represents /e/. In Vietnamese phonology, diacritics can be added to form five forms to represent five tones of ê:

• Ề ề
• Ể ể
• Ễ ễ
• Ế ế
• Ệ ệ

In Welsh, ê represents long stressed e [eː] if the vowel would otherwise be pronounced as short [ɛ]: llên [ɬeːn] "literature", as opposed to llen [ɬɛn] "curtain", or gêm [ɡeːm] "game", as opposed to gem [ɡɛm] "gem, jewel". That is useful for borrowed words with a final stress like apêl [apˈeːl] "appeal".

In Popido, a fictitious dialect of Esperanto made by Manuel Halvelik for use in literature, ê represents /ə/. It is only used epenthetically to break consonant clusters, especially before grammatical suffixes.
