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 at the end of the 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 folllwed by a /ch/ sound at the end of a baseword, it will be spelled TCH.
These are great words to add to a Spelling Journal.
