2 syllables: eigh, teen. Stress on eigh.
/ˈeɪtiːn/
Say it backEighteen is a number word formed from the combination of “eight” and the suffix “-een,” representing twenty minus two. It functions as a cardinal numeral and is used to specify the quantity 18 in counting, ages, dates, and measurements. The pronunciation compresses the two morphemes into a single syllable-time unit with a distinct final vowel. In everyday speech it often blends with surrounding sounds in rapid conversation.
- Mispronounce the final /tiːn/ as /tin/ or /tiən/, leading to a shorter or clipped ending. Correct by articulating a crisp /t/ release and holding /iː/ long enough. - Flattening /eɪ/ into a pure /e/ or /ɛ/; practice with the face in a relaxed jaw position and keep the tongue starting point high for the diphthong. - Stress error: stressing the first syllable (EE-teen) or distributing stress equally; fix by practicing the two-syllable rhythm with primary stress on TEEN and a soft onset on eigh-.
"I’m turning eighteen next month and can finally get a driver’s license."
"The concert starts at eighteen hundred hours in military time."
"We have eighteen cookies left, so you can take one."
Pronounce it as /ˌeɪˈtiːn/. The first syllable carries a light secondary stress in careful speech, but the primary stress falls on the second syllable: eigh-TEEN. Start with the diphthong /eɪ/ as in “face,” then a clear /t/ stop, and finish with a long /iː/ as in “seen.” In fast speech you may hear it as /ˈeɪtiːn/ with reduced second-stress emphasis. See IPA: US /ˌeɪˈtiːn/, UK /ˌeɪˈtiːn/, AU /ˌeɪˈtiːn/.
Common errors include mispronouncing the /tiːn/ as /tin/ with a tapped /t/ or a short vowel, or flattening the /eɪ/ to a pure /e/ or /ɛ/. Another mistake is placing stress on the first syllable (EE-teen) instead of the second (eigh-TEEN). To correct: practice the clean /eɪ/ glide into a crisp /t/, then a long /iː/; keep the /t/ release audible and hold the /iː/ slightly longer. Use minimal pairs like “eight” vs “eighteen” to hear the contrast.
In US, UK, and AU, /ˌeɪˈtiːn/ remains, but vowel quality varies slightly. US tends toward a darker, slightly tensed /iː/ and stronger interdental flaps in connected speech; UK tends to crisper t-release with a lighter /ɪ/ onset before the long vowel, and AU can have a more centralized final vowel and a slightly broader diphthong onset. Rhotic influence is minimal here since the word lacks post-vocalic R; differences are mainly vowel quality and timing of the /t/ release. IPA: US/UK/AU /ˌeɪˈtiːn/.
The difficulty lies in smoothly blending the /eɪ/ glide into the /tiːn/ with a clear /t/ release and a long /iː/. The alveolar plosive /t/ followed by the long /iː/ requires precise tongue-tap timing to avoid a blend that sounds like /tiːn/ with weak release. Also, the /eɪ/ diphthong can be misarticulated as a pure /e/ or shortened in rapid speech. Focus on the two-segment transition and maintain a strong final vowel.
Note that the 'gh' in eighteen historically hints a mouth position that resembles a gentle /ɡ/ or a glide, but in modern pronunciation there is no sound corresponding to gh; you simply glide from /eɪ/ into /tiːn/ with a firm /t/ release. The key is to avoid inserting a schwa and to keep the /tiːn/ tight and clearly enunciated, especially in careful speech. IPA reminder: /ˌeɪˈtiːn/.

- US: slight rhotic influence is minimal; emphasize the /eɪ/ with a bright start and a clear /t/ release; /tiːn/ should be held with a long, tense vowel. - UK: crisper initial offglide, lighter /t/ release, maybe less vowel lengthened; aim for a precise /tiːn/ with a clean hypoarticulated /t/. - AU: slightly more centralized vowel quality in /iːn/ and a warmer, broader /eɪ/; ensure the final /n/ is light but audible. IPA anchors: /ˌeɪˈtiːn/ across dialects; maintain the /t/ aspirated in careful speech and a clear glide into the long /iː/.
The word eighteen comes from Old English eight + -teen, a productive suffix in Middle English that forms ‘teen-words’ for numbers 13–19. The Old English form is eahta (8) and tēon (teen, ‘ten’ or ‘ten-based suffix’), with the combined word eahta-tēne evolving into eighteen. It shares a common Germanic heritage with Dutch achttien and German achtzehn, both formed through the base eight plus a Germanic -teen/-zehn suffix. The sequence for the teens (thirteen to nineteen) in English reflects a historical shift from a base-ten word system to a decimal place-value system, where -teen signified multiples of ten in older stages but became a nominal suffix for thirteen to nineteen in Early Middle English. The first known use in its modern form appears in Middle English texts, where eighteen is attested as eĝtene or eĝtien in various spellings, converging into the current spelling by Early Modern English. The pronunciation consolidates the /eɪt/ (as in eight) with the final /iːn/ sound, producing a single, smooth syllable with a nasal coarticulation in rapid speech. The historical evolution shows a shift from two disyllabic components to a single, rhyming, inherited numeral used in both counting and calendrical contexts.
