Why 'Island' and 'Knife' Hide Silent Letters

English spelling often freezes an older pronunciation in place even after the sound disappears from speech. 'Island' once had no S at all in its older English form, but writers added one centuries ago to match the unrelated Latin word 'insula' — so the S stayed in the spelling even though nobody says it. 'Knife', 'knee', and 'know' all kept their silent K from a time when English speakers really did pronounce it, before that sound quietly dropped out of the language. None of this affects how you should say these words today — 'island' is simply 'eye-land', and 'knife' is simply 'nife' — but recognizing the pattern helps you stop second-guessing yourself every time you meet a word with an unexpected letter. Try this: write down five English words you've mentally mispronounced because of unusual spelling, say them the correct way three times each, and move on with confidence. These quirks are part of English's charm, not a sign you're doing something wrong.
