The "CH" is a consonant digraph and it pronounces like a J butin a voiceless tone. The examples are chair, chain, chat, chart,chin, chop, church, change, etc. This is a pretty common CHpronunciation.However, sometimes, the CH remains the C sound like character,chemical, chaos, ache, chrome, etc. Typically, when the C isfollowed by an E, I or Y, then it'll become a soft C which soundslike an S. However, if we wanted the C to be hard but the followingletters would soften the C, then that's when the CH remains the Csound like chemical, orchid, orchestra, etc. These words mightsounds like it makes a voiceless J sound, but that's exceptionaldue to these reasons. If these words didn't have an H, then the Cmight soften as we can see what's the following letter, which wedon't expect in these words as it'll sound odd. Sometimes, if thefollowing letter would soften the C but we want the hard C, we canuse a K instead like kid, kind, king, kill, kiss, keen, kite, keep,etc. This is a pretty tricky pronunciation because if we see a CH,there's no visible clue and it's quite a hidden clue of whether theword originally makes a voiceless J sound or if the word shouldmake a C sound but the following letters would soften, which wecan't tell about. If it's about making the F-ending word's plural,then it's easier because there's a clue that it'll be "ves".However, if the CH is followed by an L or R like chlorine,chronology, chrome, chromosome, etc., then that's also when the CHwill remain the C sound, then that's a visible clue. However, thereare some exceptions that the CH remains a C sound although thesereasons weren't applied like character, charisma, anchor, mechanic,school, stomach, tech, etc. In these words, the following lettersdoesn't soften the C and the CH isn't followed by an L or R, sothat's exceptional.Sometimes, there's something called a "soft CH". When the C isfollowed by an E, I or Y, then the C would soften, which would makean S sound. Soft CH is when the C makes and SH sounds andsometimes, although the CH isn't followed by an E, I nor Y, itmight make a soft CH sound like charade, champagne, chute,parachute, chartreuse, etc. which sounds quite unusual and it makesit quite more challenging because when you come up with a CH, itseems like it might make a voiceless J sound or C sound but youmight be surprised that it might be a soft CH which makes an SHsound. The examples of soft CH are charade, chute, parachute, chef,Michelle, Michigan, machine, chalet, champagne, chevron,chartreuse, etc.
