The letter C can also be followed by the letters R, L, T and
H. When it’s followed by an R, L or an T, it’s simply pronounced like a K:
critique — critic (pronounced “krih-teek”)
clavier — keyboard (pronounced “klah-vee-yeh”)
instructif — instructive (pronounced “an-strook-teef”)
When the letter C is followed by a H, the combination of CH
is usually pronounced like the SH in the English words ship or show.
champagne — champagne (pronounced
“shom-pan-yeugh”)
cher — expensive (pronouced “share”)
chose — thing (pronounced “showz”)
However, there are a few words that contain a CH, which is
pronounced like a K. They’re much less common, though:
technique — technical (pronounced “tek-neek”)
chœur — choir (pronounced “kur”)
archéologie — archaeology (pronounced “ar-keh-oh-loh-jee”)
