Silent letters in English

Silent letters are letters that you can’t hear when you say the word, but that are there when you write the word.

Silent letters can distinguish between homophones, e.g. in/inn; be/bee; lent/leant. This is an aid to readers already familiar with both words.
Silent letters may give an insight into the meaning or origin of a word, e.g. vineyard suggests vines more than the phonetic ‘vinyard’ would.
Silent letters help to show long vowels e.g. rid/ride
Silent letters help to show ‘hard’ consonants e.g. guest/gest
They can help to connect different forms of the same word e.g. resign/resignation
