What words disobey the ch or tch ending after a short vowel?

You're likely thinking about the spelling rule that states that after a short vowel, you typically use "ch" to represent the /ch/ sound. However, there are some exceptions to this rule.

Here are some words that disobey this rule:

* "which" - The "ch" in this word is pronounced like a "k" sound.

* "stitch" - The "tch" in this word is pronounced as a /ch/ sound.

It's important to remember that language is full of inconsistencies. While the general rule holds true for many words, there will always be some exceptions.
