Silent Letter Words

Silent letters are the ghosts of English spelling. They sit inside words unpronounced — the K in KNIGHT, the B in DEBT, the GH in THOUGH — usually because the spelling was fixed centuries ago and pronunciation kept moving. Every silent letter tells a small story about French borrowing, Old English sound change, or 16th-century printers trying to look Latin.

This page gathers hundreds of English words with silent letters, grouped by pattern, plus tips on how to spot them, why they exist, and how they land in word games. Every word is a real dictionary entry drawn from the ENABLE list.
