Huh.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Diaeresis_%28diacritic%29#English" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Diaeresis_%28diacritic%29#Engl...</a><p>&gt; The grave accent and the diaeresis are the only diacritics native to Modern English... The use of both, however, is considered to be largely archaic.
The diaeresis mark is sometimes used in English personal first and last names to indicate that two adjacent vowels should be pronounced separately, rather than as a diphthong. Examples include the given names Chloë and Zoë... it is far less commonly used in words such as coöperate and reënter except in a very few publications—notably The New Yorker.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Grave_accent#English" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Grave_accent#English</a><p>&gt; The grave accent, although not commonly applied to any English words, is sometimes used in poetry and song lyrics to indicate that a vowel usually silent is to be pronounced, in order to fit the rhythm or meter. Most often, it is applied to a word ending with -ed. For instance, the word looked is usually pronounced &#x2F;ˈlʊkt&#x2F; as a single syllable, with the e silent; when written as lookèd, the e is pronounced: &#x2F;ˈlʊk.ɨd&#x2F; look-ed). It can also be used in this capacity to distinguish certain pairs of identically spelled words like the past tense of learn, learned &#x2F;ˈlɜrnd&#x2F;, from the adjective learnèd &#x2F;ˈlɜrn.ɨd&#x2F; (for example, &quot;a very learnèd man&quot;).
