Silent and invisible letters in English

Silent letters constitute a notorious phenomenon in English: in wréstle, for example, only four out of the seven letters are actually sounded (*résl), and there can be strings of them in place names, exemplified by the trio Léicester, Glóucester and Worcester, pronounced Léster, *Glóster and *Wùster. (The accents show stress and pronunciation, see English spellings; * is placed before an incorrect spelling.)

Silent letters can be misleading, as in Thaîland and îsland, which rhyme, or they can be easy to ignore ("redundant"), as in wróng, yeôman, and lôw.

They can serve to distinguish between words that sound the same:

knôw knowledge = nô negative

knót tie = nót negative

wráp parcel = ráp knock, talk

wrîte read = rîght correct = rîte ritual

chéck verify = BrE chéque money

Some typical examples

• b finally after m or before final t (-mb -bt)
• g or k initially before n (gn-, kn-)
• gh finally or before final t (-gh -ght)
• l after à and before final f or m (-lf -lm)
• n finally after m (-mn).
