- Confusing the -teen- portion with the base 'fifth', leading to a shortened word. Maintain the /tiːn/ vowel sequence and do not reduce it to /tiː/ or /tiːə/. - Dropping the final dental sound; some speakers end with a simple /t/ or /tʃ/ instead of a precise -nθ or -ntʃ. - Misplacing stress by moving it to the second syllable; keep primary stress on the first syllable. Correction tips: practice the exact syllable-by-syllable rhythm: FI-FTEEN-TH with clear separation and ensure the final dental/fricative is audible. Use minimal pairs like 'fifth' vs 'fifteenth' to train length, voicing, and place.

"He spoke on the fifteenth of every month."
Pronounce it as /ˈfɪfˌtiːntʃ/ in many US varieties or /ˈfɪfˌtiːnθ/ in some UK/AU usage. The primary stress is on the first syllable, with a secondary pause-like emphasis on the second syllable. The ending should be an aspirated alveolar plosive + voiceless fricative blend: -ntʃ in many dialects, or -nθ in others. Listen for the final 'th' or 'tch' sound—this is the key distinguishing feature.
Common errors include misplacing the stress on the second syllable (fi-FTH-eenth) and simplifying the ending to -th or -teth without the proper dental-fricative or affricate. Another pitfall is conflating with 'fifth' by shortening the word or dropping the -teen element. Correct by keeping primary stress on first syllable and producing -tiːnθ or -tiːntʃ accurately: end with the dental fricative θ or the palato-alveolar affricate ʧ before a voiceless stop.
In US, you’ll often hear /ˈfɪfˌtiːnt/ or /ˈfɪfˌtiːntʃ/ with final -nt and a lighter -h. UK varieties may render the ending as /-nθ/ or /-n(θ)/ with a softer dental fricative; AU often mirrors UK but can lean toward /-nt/ or /-ntθ/ depending on speaker. The central feature is the -teen-th sequence: keep /tiː/ clearly before either /nθ/ or /ntʃ/ depending on region; rhoticity and vowel quality in the first syllable can subtly shift the overall tension.
The difficulty lies in the rapid transition from the /tiː/ vowel cluster to the dental consonant cluster at the end. You have a three-part sequence: fi- (unstressed mid vowel) + -fth-/ -nteenth, culminating in a dental fricative or affricate. The tongue must glide from the high front position for /ɪ/ to the alveolar ridge for /t/ and then to the dental place for /θ/ or the palato-alveolar /tʃ/. Precise tongue-tip placement and air control ensure a crisp ending.
Is the final consonant a dental fricative θ or a palatal affricate ʧ across forms? The answer depends on dialect: many speakers articulate the final -th as θ (fifteen-th) or shift to ʧ (fifteenth) in fluent speech. The distinction matters in careful speech: practice both variants, but aim for a clear dental fricative in formal contexts and a natural, rapid -nt/ -nθ ending in conversational settings.

- US: tends toward rhotic accent with a slightly darker /ɪ/ in first syllable; final -θ is less common, more often an -nt or -ntʃ. - UK: distinct -θ or -tʃ endings; non-rhotic, so you may hear a crisp alveolar /t/ before /θ/. - AU: similar to UK but can show variation in vowel quality; softer finishing /θ/ or a light /tʃ/ depending on speaker. IPA anchors: US /ˈfɪfˌtiːnt/ or /ˈfɪfˌtiːnθ/, UK /ˈfɪfˌtiːnθ/ or /ˈfɪfˌtiːntʃ/. Practice tips emphasize clear tongue-tip contact and consistent timing of the -teen + ending.
Fifteenth derives from Old French cinquantaine? (No, correction: The form is from Middle English fifteenth, from Old English fiftēn? Actually eight: The base number fifteen comes from Old English fiftēn, formed from fift- (five) + -ēn (suffix forming ordinals). The ordinal suffix -þ (–th) attaches to the numeral, yielding fifteenth. The morphological path mirrors other ordinal formations in English: base numeral + the formal ordinal ending. The earliest attested forms appear in late Old English and Middle English manuscripts as fiftēnte? The semantics solidified as the ordinal position after fourteenth and before sixteenth, used in calendars, numbered lists, and fractions-based contexts. Over time, pronunciation glided with Great Vowel Shift effects, influencing the diphthong in five and the unstressed -eenth cadence, while the historical spelling retained -teenth. First known uses appear in legal and liturgical texts where precise sequence identification was required, later expanding into everyday enumeration and formal writing.
