Why English Spelling Doesn't Match Pronunciation (and Why That's Extra Hard for Korean Speakers)
"Knight," "through," "colonel," "island" — none of them sound the way they're spelled, and for a reader used to Hangul, that isn't a minor inconvenience.

A frustration that's easy to underestimate
"Colonel" is pronounced like "kernel." "Island" has a silent s. "Through," "though," "thought," and "tough" share four letters and rhyme with almost nothing. For a Korean speaker, this isn't a small quirk to shrug off — it's a genuine mismatch with what writing is supposed to do, and it causes real, specific trouble: mispronouncing words you've only ever seen in print, or failing to recognize a word you know perfectly well when it's spoken aloud.
Why Hangul sets a different expectation
Hangul was deliberately designed, in the 15th century, so that a word's spelling maps almost exactly onto its pronunciation — a rare thing among the world's writing systems. A Korean reader can sound out an unfamiliar word correctly on sight almost every time, because the system was built for exactly that. English spelling was never designed at all; it accumulated over roughly a thousand years, absorbing words from Old English, Old Norse, Norman French, and Latin, each arriving with its own spelling habits and rarely getting fully reconciled with how English pronunciation kept drifting afterward. "Knight" still has its silent k and gh because that's genuinely how it was pronounced centuries ago — the spelling fossilized while the sound kept changing.
Why this creates a specific, avoidable trap
A reader used to a phonetic system reasonably expects that decoding a word letter by letter will produce its correct pronunciation, and keeps applying that strategy in English even after it repeatedly fails. This shows up as two separate problems: mispronouncing real words with unpredictable spelling (reading "colonel" as it's spelled instead of as it's said), and, just as often, not recognizing a familiar spoken word because its spelling looked nothing like what the ear expected. Neither is a vocabulary gap — the word is already known. It's a mismatch between two systems that Korean never trained a reader to expect.
Why more phonics rules aren't really the fix
English does have spelling patterns, and they're worth knowing, but there are enough genuine exceptions that rules alone can't get you all the way to fluent, confident reading. What actually works is the same thing that works for native English-speaking children: enough repeated exposure to each specific word in print that it's recognized instantly as a whole shape, the way a fluent reader doesn't sound out "the" or "said" letter by letter every time. This is sight-word recognition, and it's built by volume of reading, not by memorizing more spelling rules. Listening while reading accelerates it directly, since it pairs the correct sound with the exact spelling at the same moment, closing the gap in the one place phonics rules can't reach.
Where to start
Read an A2-level story with the audio playing alongside the text — every irregular word you meet that way gets its correct sound attached directly to its spelling, which does more for real recognition than any list of spelling exceptions.
