Italian Alphabet - C and G

C and G

Normally, ⟨c⟩ and ⟨g⟩ represent the plosives /k/ and /ɡ/, respectively, unless they precede a front vowel (⟨i⟩ or ⟨e⟩) when they represent the affricates /tʃ/ (like English ch) and /dʒ/ (like English j).

The letter ⟨i⟩ may also function merely as an indicator that the preceding ⟨c⟩ or ⟨g⟩ is soft, e.g. cia (/tʃa/), ciu (/tʃu/). When the hard pronunciation occurs before a front vowel, digraphs ⟨ch⟩ and ⟨gh⟩ are used, so that ⟨che⟩ represents /ke/ or /kɛ/ and ⟨chi⟩ represents /ki/. In the evolution of the Latin language, the postalveolar affricates /tʃ/ and /dʒ/ were contextual variants of the velar consonants /k/ and /ɡ/. They eventually came to be full phonemes, and the said orthographic practice was introduced to distinguish them. The phonemicity of the affricates can be demonstrated with the minimal pairs:

The trigraphs ⟨cch⟩ and ⟨ggh⟩ are used to indicate geminated /k/ and /ɡ/, respectively, when they occur before ⟨i⟩ or ⟨e⟩; e.g. occhi /ˈokːi/ ('eyes'), agghindare /aɡːinˈdare/ (to dress up).

⟨G⟩ is also used to mark that a following ⟨l⟩ or ⟨n⟩ is soft (this is not always true in loanwords from other languages). With ⟨l⟩, a following ⟨i⟩ is also necessary, though this may be stressed or unstressed: famiglia /faˈmiʎʎa/ ('family').

The digraph ⟨sc⟩ is used before ⟨e⟩ and ⟨i⟩ to represent /ʃ/; before other vowels, ⟨sci⟩ is used. Otherwise, ⟨sc⟩ represents /sk/, the ⟨c⟩ of which follows the normal orthographic rules explained above.

Other than a few Northern Italian dialects, intervocalic /ʎ/, /ɲ/, and /ʃ/ are always geminated and no orthographic distinction is made to indicate this.
