The TCH rule in English spelling dictates when to use "tch" instead of "ch" at the end of a word.
Explanation of the TCH Rule
The TCH rule applies when a short vowel sound immediately precedes the /ch/ sound at the end of a word. According to the reference (Part of a video titled Words Ending -ch and -tch | Spelling Rule | EasyTeaching - YouTube), if a short vowel sound comes directly before the "ch" sound (represented as "chirp" in the video), then you spell it with "tch".
Examples Illustrating the Rule
Here are some examples to clarify the TCH rule:
- Catch: The short /a/ sound precedes the /ch/ sound, so we use "tch."
- Fetch: The short /e/ sound precedes the /ch/ sound, so we use "tch."
- Pitch: The short /i/ sound precedes the /ch/ sound, so we use "tch."
- Blotch: The short /o/ sound precedes the /ch/ sound, so we use "tch."
- Clutch: The short /u/ sound precedes the /ch/ sound, so we use "tch."
When NOT to Use "TCH"
It's important to understand when not to use "tch". Here are some situations:
- Long Vowel Sounds: If a long vowel sound precedes the /ch/ sound (e.g., "reach", "beach").
- Diphthongs: If a diphthong (a combination of two vowel sounds) precedes the /ch/ sound.
- Consonant Before "ch": If a consonant precedes the "ch" sound (e.g., "bench," "ranch").
Summary
| Rule | Spelling | Example |
|---|---|---|
| Short vowel before /ch/ | TCH | Catch, fetch |
| Other cases | CH | Beach, bench |
