発音の仕方：口を軽く閉じ、唇だけを開けます。そして、閉じている前歯の隙間から空気を強めに外に向かって出します。そのときの声にならない音がこの音です。
[s]音とつづりの関係は、当然ながら ‘s’ が基本ですが、’ss’ や ‘e’ や ‘i’ を伴った ‘c’ も多く見られます。’e’ や ‘i’ を伴わない ‘c’ は [s] ではなく、[k] と発音します。つまり、’ce’ と ‘ci’ と綴られる場合のみ [s] と発音し、’a’, ‘u’, ‘o’ を伴うときや、’cc’ の最初の ‘c’ 、また、母音字を伴わないときの ‘c’ はすべて[k]音です。
*Silent ‘s’ ：aisle, island, corps（p, s共に無音。複数の場合は [z]音。pは無音のまま）, debris（複数の場合は [z]音）などが主なもので、非常に少ない。
次回は [z]です。
