The phonogram CH and TCH
Someone called today asking if there was a rule to govern the spelling of the sound /ch/ after a single short vowel at the end of the word. She pointed out it can be spelled with a CH or a TCH.
Logic of English already has a list of the thirty-five words that end in TCH.
However, I decided to look up how many words use the phonogram CH after a short vowel at the end of a base word instead.
The great news is that there are only six.
If it is not one of these six, if you hear a short vowel followed by a /ch/ sound at the end of a base word, it will be spelled TCH.
These are great words to add to a Spelling Journal.
For your reference, here are the base words that end in TCH:
