how do you spell the letter y in french
Y In French orthography, ⟨y⟩ is pronounced as [i] when a vowel (as in the words cycle, y) and as [j] as a consonant (as in yeux, voyez). It alternates orthographically with ⟨i⟩ in the conjugations of some verbs, indicating a [j] sound. In most cases when ⟨y⟩ follows a vowel, it modifies the pronunciation of the vowel: ⟨ay⟩ [ɛ], ⟨oy⟩ [wa], ⟨uy⟩ [ɥi]. The letter ⟨y⟩ has double function (modifying the vowel and [j] or [i]) in the words payer, balayer, moyen, essuyer, pays, etc., but in some words it has only a single function: [j] in bayer, mayonnaise, coyote; modifying the vowel at the end of proper names like Chardonnay and Fourcroy. In French ⟨y⟩ can have a diaresis (tréma) as in Moÿ-de-l'Aisne.
