Why 'Through,' 'Though,' and 'Tough' Don't Rhyme

Greek spelling matches its sounds closely and reliably, so it can feel baffling that English words ending in '-ough' go in wildly different directions: 'through' rhymes with 'blue', 'though' rhymes with 'go', and 'tough' rhymes with 'stuff'. Add 'bough' (rhymes with 'cow') and 'thought' (rhymes with 'fault'), and you've got five completely different pronunciations hiding behind one four-letter spelling pattern. This isn't a sign that English pronunciation is random everywhere — most spelling patterns are far more reliable than this one — but '-ough' is a genuine historical leftover with no internal logic left to learn, only memorization. Try this: write down these five words, say each one out loud using its real pronunciation, and group them by rhyme. Add any new '-ough' word you meet to this list going forward. Treating oddities like this as a short, finite list to memorize — rather than a sign you're missing some hidden rule — will save you a lot of unnecessary frustration.
