Hard and soft C
In the Latin-based orthographies of many European languages (including English), a distinction between hard and soft ⟨c⟩ occurs in which ⟨c⟩ represents two distinct phonemes. The sound of a hard ⟨c⟩ (which often precedes the non-front vowels ⟨a⟩, ⟨o⟩ and ⟨u⟩) is that of the voiceless velar stop, [k] (as in car) while the sound of a soft ⟨c⟩ (typically before ⟨e⟩, ⟨i⟩ and ⟨y⟩), depending on language, may be a fricative or affricate. In English, the sound of soft ⟨c⟩ is /s/ (as in "citrus").
