- You’ll often over-emphasize the middle /ɛ/ or misplace the primary stress on the first syllable, producing IN-fidelity instead of in-FED-uh-li-ty. To fix, anchor the stress on the second syllable: practice saying in-FED-uh-li-ty slowly, then gradually speed while keeping the beat. - The final -ity can get shortened to -i- or pronounced as -ty; keep it as a light, separate syllable /ti/ rather than /tiː/ or merging with the preceding vowel. - Some speakers merge the /d/ and /l/ into a single sound; keep the /d/ with a short stop before the light /l/ - practice with a syllabic rhythm: ɪn - ˈfɛd - lɪ - ti, with clear, shorter /l/ transition.
How to Pronounce Infidelity
"Her confession of infidelity damaged the trust in their marriage."
"The study explored how infidelity affects long-term relationship satisfaction."
"He faced rumors of infidelity after pictures appeared online."
You say iN-FED-ə-lə-tē, with primary stress on the second syllable: /ˌɪnˈfɛdəlɪti/. Start with a short i sound, move into a stressed 'FED' syllable, then a schwa-lite 'ə', and finish with 'lɪti'. The sequence is two unstressed syllables before the main beat, then a light final 'ee' sound. If you use US pronunciation, it matches /ˌɪnˈfɛdəlɪti/.
Common errors: (1) Misplacing primary stress on the first syllable instead of the second (say IN-fidelity). (2) Slurring the middle syllable so it sounds like 'fed' becomes 'fed-uh'. (3) Dropping the final -ty into a quick 'tee' or pronouncing it as 'ti' instead of the unstressed 'ti' sound. Correction tips: emphasize the second syllable with a clear /ˈfɛd/ and keep the final -ti as /ti/ or /ti/ with a light, quick schwa. Practice slow, then speed up while maintaining the stress pattern.
US: /ˌɪnˈfɛdəlɪti/ with rhotic /r/ not present in this word. UK: /ˌɪnˈfɛdɪəlɪti/ shows a slight schwa in the middle and a less pronounced /l/ depending on speakers. AU: similar to US but with a more clipped 'i' in the second syllable and vowel quality shift toward /ɪ/ or /eɪ/ for some speakers. In all accents, the second syllable bears primary stress; the middle vowel is typically /ɛ/ or /eɪ/ depending on speaker. Mouth positions adjust accordingly: keep lips neutral for /ɪ/ and open wider for /ɛ/.
Two main challenges: the 2nd syllable /ˈfɛd/ requires clear voicing and a short, sharp /ɛ/. The sequence -del- can blur into /də/ if the tongue relaxes; keep a light /l/ and an almost schwa-like /ə/ between /d/ and /l/. The final -ity adds an extra syllable with a light /i/; avoid turning it into /ti/ or /tiː/—keep it /ti/ as a quick, unstressed ending. Consistent stress placement and precise articulation of /d/ and /l/ help a lot.
There are no silent letters in infidelity; every letter contributes to the sound pattern. The challenge is not silence but the subtle vowel and consonant transitions: the /f/ blends into the / ɛ/ then into /d/ and finally the /lɪti/ sequence. Practicing fluidly across those segments helps avoid hesitation or misarticulation. Remember: the letters guide distinct syllables with clear beats, even though some vowels are reduced in casual speech.

- US: rhoticity isn’t a factor in this word; vowels tend to be tenser; emphasize /ɛ/ in FED. - UK: slightly more clipped vowels and a lighter /t/; some speakers may reduce /ɪ/ to a near-schwa in the final -ɪti. - AU: vowel height can be a touch higher; /ɪ/ and /ɛ/ may shift toward near-close front unrounded vowels. Across all, keep the second syllable strong, but the final -i-ty remains light and quick. IPA anchors: US /ˌɪnˈfɛdəlɪti/, UK /ˌɪnˈfɛdɪəlɪti/, AU /ˌɪnˈfɛdɪəlɪti/. - Focus on the /fə/ or /dɪ/ sequence; maintain tongue position to avoid a clumsy /də/ blend.
Infidelity comes from Middle French infidélité, from infidèle (unfaithful person), which itself derives from Latin infidelis (unfaithful, not faithful). The Latin root infidel- means not faithful, from in- (not) + fidēlis (trustworthy). The English adoption occurred in the 16th century, originally relating to religious faithlessness or betrayal of vows, later broadening to describe sexual or emotional betrayal in intimate relationships. Over time, infidelity has carried legal, moral, and psychological weight, often used in divorce proceedings, counseling contexts, and discussions of romantic ethics. The term's connotations emphasize a breach of trust and commitment more than mere sexual activity, though sexual infidelity is the common reference point. First known uses appear in early modern English writings addressing marital fidelity and the social norms surrounding marriage and religious obligations. In contemporary usage, infidelity can be discussed in clinical terms (attachment, trust repair) or in everyday talk, frequently signaling relational fracture and the process of healing. The word’s evolution mirrors changing attitudes toward monogamy, privacy, and the boundaries of romantic relationships.
