when did the letter j become apart of the alphabet
J In English, ⟨j⟩ most commonly represents the affricate /dʒ/. In Old English, the phoneme /dʒ/ was represented orthographically with ⟨cg⟩ and ⟨cȝ⟩.[5] Under the influence of Old French, which had a similar phoneme deriving from Latin /j/, English scribes began to use ⟨i⟩ (later ⟨j⟩) to represent word-initial /dʒ/ in Old English (for example, iest and, later jest), while using ⟨dg⟩ elsewhere (for example, hedge).[5] Later, many other uses of ⟨i⟩ (later ⟨j⟩) were added in loanwords from French and other languages (e.g. adjoin, junta). The first English language book to make a clear distinction between ⟨i⟩ and ⟨j⟩ was published in 1633.[6] In loan words such as raj, ⟨j⟩ may represent /ʒ/. In some of these, including raj, Azerbaijan, Taj Mahal, and Beijing, the regular pronunciation /dʒ/ is actually closer to the native pronunciation, making the use of /ʒ/ an instance of a hyperforeignism.[7] Occasionally, ⟨j⟩ represents the original /j/ sound, as in Hallelujah and fjord (see Yodh for details). In words of Spanish origin, where ⟨j⟩ represents the voiceless velar fricative [x] (such as jalapeño), English speakers usually approximate with the voiceless glottal fricative /h/.
