In US pronunciation: /koʊˈɪnsɪdɪd/ with primary stress on the third syllable. Break it as co-in-ci-ded; the middle syllable has a short /ɪ/; the final -ded is /dɪd/ as a syllabic ending when spoken in careful speech. In connected speech, the middle /n/ can link to the following /s/ for smoother flow, so you might hear /koʊˈɪnsɪdɪd/ or /kəˈɪnsɪdɪd/ depending on speaker. IPA references: US /koʊˈɪnsɪdɪd/; UK /kəʊˈɪnsɪdɪd/; AU /koːˈɪnsɪdɪd/.
Common errors include flattening the stress to the first syllable (co-), pronouncing the second syllable as a long /iː/ or misplacing the /ɪ/ in the third syllable, and finishing with a soft or silent -ed. To correct: keep the primary stress on the third syllable (co-in-SI-ded) and pronounce the final -ed as /ɪd/ in careful speech, or /d/ in rapid speech. Focus on the sequence /koʊ/ or /kəʊ/, /ɪn/ or /ən/, /sɪ/ and /dɪd/.
In US English, /koʊˈɪnsɪdɪd/ with /oʊ/ and /ɪ/ vowels; rhotic linking may alter the initial vowel slightly in casual speech. UK English tends toward /kəʊˈɪnsɪdɪd/ with a shorter /əʊ/ in some regions, and the /ɪ/ in the second syllable can be reduced in fast speech. Australian English often uses /koˈɪnsɪdɪd/ with a more centralized American-like second syllable and a less pronounced rhoticity; still retains the /ˈɪ/ in the third syllable. All share the /dɪd/ final, but vowel qualities and stress timing vary.
The difficulty lies in the multi-syllabic rhythm and the placement of the stress on the third syllable, not the first. Also, the sequence -in-sid- combines a nasal /n/ with a high-front /ɪ/ followed by a reduced /dɪd/ ending, which can blur in rapid speech. Additionally, non-native speakers may mispronounce the /oʊ/ as /ɔ/ or reduce /ɪ/ to a schwa. Practice the crisp articulation of the /koʊ/ or /kəʊ/ onset, the /ɪn/ nucleus, and the final /sɪdɪd/ cluster.
The word has a three-syllable core with a mid- to late-stress pattern: co-in-CIDed in some analyses; more commonly co-in-CIDed or kə-ɪn-SI-dəd depending on dialect. The suffix -ed is pronounced as /ɪd/ in careful speech, which requires a quick, light /d/ followed by a brief /ɪ/ before the final /d/. Understanding the syllable boundary helps you avoid merging /s/ and /d/ into a single sound.
🗣️ Voice search tip: These questions are optimized for voice search. Try asking your voice assistant any of these questions about "coincided"!
Coincided derives from late Latin coincidere, formed from com- (together) and incidere (to happen, to fall upon). The root incidere is related to incident and to occur, reflecting the sense of events happening at the same moment. The English adoption likely passed through French or Latin-influenced channels in the 17th–18th centuries, aligning with other -cede or -sid- verbs that describe meeting or coming together in time. Early uses emphasized conjunction of events or occurrences in time, gradually broadening to describe synchronized events, schedules, or outcomes. The morphological form -ed marks past tense/perfect aspect, indicating that the alignment of times occurred in the past. Over time, coincide gained a slightly formal or literary tone, frequently used in academic, scientific, or analytical prose, but remains common in everyday narration when describing parallel timings or matched occurrences.
