CH and TCH Phonograms

The phonograms CH and TCH both represent /ch/ or /ʧ/ using the International Phonetic Alphabet. Logic of English Spelling Rule 27 tells us when to use TCH for spelling:

TCH is used only after a single vowel which says its short or broad sound.

Spelling Rule 27 does not address words where CH is used after a single short or broad vowel. Interestingly, there are only a few words where CH is used after a single vowel which says its short or broad sound:

CH

However, there are many words spelled with a TCH after a single short or broad sound. These are fantastic words to add to your Spelling Journal:

TCH

botch fetch latch sketch switch
butch glitch match snatch twitch
