Pronunciation Guide • QuickPronounce Team • 10 min read • January 9, 2026
In short: Silent letters are spelled but not spoken: the B in doubt and comb, K in knight and know, L in walk and calm, P in psychology and receipt, G in sign and campaign, H in honest and hour, T in listen and castle, and W in write and wrong. Each follows a rule, so you can predict silence instead of memorizing words.
