How to pronounce “thorough”
Thorough is pronounced /ˈθɜːroʊ/. It has 2 syllables, and the beat falls on the first one — θɜːr. Below: the syllable split, native audio in both accents, the mistake people actually make with this word, and every individual sound in it explained.
Syllables and stress
Split it into 2 beats. The highlighted syllable is the strong one: say it louder, longer and a touch higher in pitch, and let the others fall away. English is a stress-timed language, so getting θɜːr in the right place matters more to a listener than getting every vowel perfect.
Stress pattern Oo — capital letters mark the stressed beats.
The common mispronunciation of “thorough”
✗ Often said: /ˈθroʊ/ — the spelling, read straight off the page.
✓ Actually: /ˈθɜːroʊ/
Why the two come apart: it is two syllables, not one — it is not “through”. The “-ough” here is an unstressed /oʊ/, so it is “THUH-roh”.
This is why reading English aloud from spelling alone goes wrong so often: the letters of “thorough” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.
