Introduction

What is IPA?

English spelling is notoriously treacherous. The letters ough are pronounced differently in though, through, tough, cough, thought, and bough. Six spellings. Six different sounds. And that's before you get to colonel or worcestershire.

The International Phonetic Alphabet sidesteps the chaos entirely — one symbol, one sound, always. It was created in 1888 by a group of language teachers who were frankly tired of this nonsense, and it now covers every sound in every human language.

When this dictionary shows /flæʃ/ beside flash, each symbol stands for exactly one sound: /f/ as in fan, /l/ as in let, /æ/ as in bat, /ʃ/ as in ship.

To read English fluently in IPA you only need about 44 symbols — far fewer than the 26 letters that are doing their very best and failing half the time.

Reading IPA

The notation explained

Beyond the individual symbols, IPA uses a handful of conventions you'll encounter in any dictionary entry.

ˈ
Primary stress
The syllable immediately after this mark gets the main emphasis. In speech, it's louder, longer, and higher in pitch.
ˈflæʃ → FLASH
ˌ
Secondary stress
A lighter emphasis than primary. Common in longer words where two syllables both need some punch.
ˌdɪkʃəˈneri
ː
Long vowel
This colon-like mark doubles the length of the vowel before it. Compare /ɪ/ in bit with /iː/ in beat — same mouth shape, different duration.
biːt  vs  bɪt
/ /
Phonemic transcription
Forward slashes mark a broad transcription — the sound categories of English as a system, not every tiny phonetic nuance of a specific speaker.
/flæʃ/
( )
Optional sound
A sound in parentheses may or may not appear, depending on dialect, speech rate, or the sounds around it.
ˈbʌt(ə)n → button
.
Syllable boundary
A dot marks where one syllable ends and the next begins, helping clarify stress patterns and rhythm in longer words.
ˈflæ.ʃɪŋ
