Is "Witch" the Same Word as "Which"? The Two Rules Behind wh- Words

What, when, where, white, which, who, whose, whole — words you've known for years, and yet nobody ever explained what the wh is actually supposed to sound like. Some dictionaries mark it /w/, some mark it /h/, and it can look completely random.

It isn't. There are exactly two rules, and the exceptions are short enough to memorize outright.

Rule 1: Most wh- words are pronounced /w/ — the h is silent

• what /wʌt/
• when /wen/
• where /weər/
• why /waɪ/
• white /waɪt/
• which /wɪtʃ/

Look at that last one closely: "which" and "witch" are pronounced identically in modern English — both /wɪtʃ/. You didn't mishear it; they really are homophones. The same goes for whale and wail, both /weɪl/ for most speakers today.

Historically, wh had its own sound, /hw/ — a small puff of breath before the /w/. Some Scottish and Irish accents, and pockets of the American South, still keep it, which lets them distinguish which /hwɪtʃ/ from witch /wɪtʃ/. But mainstream American and British English merged the two long ago — linguists call it the "wine-whine merger." As a learner, you can safely learn only the /w/ version and skip /hw/ entirely.

Rule 2: When wh is followed by o, it's /h/ — and the w goes silent instead

This is the one group that flips the pattern, and it's short enough to learn in full:

• who /huː/
• whom /huːm/
• whose /huːz/
• whole /hoʊl/

Put them side by side and the contrast is clear: the w in where /weər/ is pronounced, but the w in whose /huːz/ isn't. These two groups look almost identical on the page and sound like opposites — which is exactly why they get mixed up.

Why this happens

Spelling doesn't reliably predict pronunciation in English — that's normal — but wh- is one of the rare cases where a single rule covers nearly everything: check whether an o follows. If it does, say /h/. If it doesn't, say /w/. The only real exception is the rare word whore, which barely comes up in everyday speech.

Practice: separate the two groups

Read these pairs back to back: where /weər/ – who /huː/, what /wʌt/ – whose /huːz/, white /waɪt/ – whole /hoʊl/. Notice how the first word in each pair rounds your lips for /w/, while the second is just a puff of air from the throat for /h/ — the lips don't move at all.

Not sure whether a wh- word takes /w/ or /h/? PHONO reads any English text through your camera and marks every word with IPA, in both US and UK audio, so you can see instantly which letter goes silent.
