What is the 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
