How to Say 30 in English: Visual Phonetics, Audio Cues, and the 21 to 30 Cheat Sheet
By Maya Lin-Takahashi
Counting in English becomes predictable once you cross into the twenties. The language uses a simple compound formula: take the base ten-word (twenty) and attach the single-digit cardinal number with a hyphen. In casual North American speech, "twenty" often undergoes elision, sounding like TWEN-ee (/ˈtwɛni/), though crisp educational settings preserve the internal /t/ (TWEN-tee).
Written style requires a hyphen between the tens and units place for every compound number between 21 and 99. Omitting the hyphen in formal prose represents a mechanical grammar error. Below is the systematic breakdown comparing written orthography, phonetic transcriptions, and conversational audio cues across the entire cluster.
| Number | Written Form | IPA Transcription | Phonetic Rhythm / Cue |
|---|---|---|---|
| 21 | Twenty-one | /ˌtwɛntiˈwʌn/ | TWEN-tee-WUN |
| 22 | Twenty-two | /ˌtwɛntiˈtuː/ | TWEN-tee-TOO |
| 23 | Twenty-three | /ˌtwɛntiˈθriː/ | TWEN-tee-THREE |
| 24 | Twenty-four | /ˌtwɛntiˈfɔːr/ | TWEN-tee-FOR |
| 25 | Twenty-five | /ˌtwɛntiˈfaɪv/ | TWEN-tee-FYVE |
| 26 | Twenty-six | /ˌtwɛntiˈsɪks/ | TWEN-tee-SIX |
| 27 | Twenty-seven | /ˌtwɛntiˈsɛvən/ | TWEN-tee-SEV-en |
| 28 | Twenty-eight | /ˌtwɛntiˈeɪt/ | TWEN-tee-AYT |
| 29 | Twenty-nine | /ˌtwɛntiˈnaɪn/ | TWEN-tee-NYNE |
| 30 | Thirty | /ˈθɜːrti/ | THUR-tee (US: THUR-dee) |
