When practicing your English pronunciation, one of the tricky areas are those of silent letters. While the rules governing which sounds remain unpronounced can feel arbitrary, the English language actually follows strict guidelines when it comes to silent letters. Use this list as a guide whenever you’re practicing your vocabulary skills, either in front of a language learning software or just by yourself.
- The letter B is silent when it’s at the end of the word and is immediately preceded by the letter M (e.g. dumb, comb).
- The letter C is silent only in words ending in “scle” (e.g. muscle).
- The letter D is silent in only three words of the language, namely sandwich, Wednesday and hendkerchief.
- The letter E is silent when used at the end of words and is immediately preceded by a consonant (e.g. mine, drive).
- The letter G is silent when followed by N (e.g. foreign, sign).
- The letters G and H are silent when used together and are followed by T (e.g. daughter, right).
- The letter H is silent when used after W (e.g. whether, why) and, sometimes, when used in the beginning of words, followed by a vowel (not always, though, so it’s tricky).
