Silent letters can make English spelling and pronunciation confusing, and “GH” is one of the biggest troublemakers. In many English words, GH is not pronounced at all, even though it appears in the spelling. Understanding silent GH will help you improve your reading, pronunciation, and spelling.
What Is Silent Letter GH?
Silent GH means the letters “g” and “h” appear in a word but are not pronounced. You simply skip the sound when speaking. The word is spoken as if the GH isn’t there.
Example:
-
Light → /laɪt/ (you don’t say the “g” or “h”)
-
Night → /naɪt/
-
Thought → /θɔːt/
When Is GH Silent?
GH is silent mostly when it appears:
1. After a vowel at the end of a word
You don’t pronounce GH in words that end with -igh, -ought, or -augh.
Examples:
-
Brought
-
Caught
- Thought
2. Before the letter “T”
GH is usually silent when followed by T.
Examples:
-
Right
-
Fight
-
Bought
-
Tight
-
Daughter
3. In the middle of some words
Sometimes GH appears in the middle of a word and stays silent.
Examples:
-
Highway
-
Slightly
-
Forethought
-
Eighty
Exceptions of GH
Sometimes GH Makes an /f/ Sound
GH is not always silent. In a few words, it sounds like /f/.
Examples:
-
Cough → /kɒf/
-
Enough → /ɪˈnʌf/
-
Laugh → /læf/
-
Tough → /tʌf/
-
Rough → /rʌf/
A good trick:
If GH comes after a short vowel (a, e, i, o, u), it often sounds like /f/.
Rarely, GH Sounds Like /g/
In some words related to German or Dutch origins, GH is pronounced like /g/.
Examples:
-
Ghost
-
Ghastly
-
Gherkin
