3 syllables: in, duc, tor. Stress on duc.
in-DUHK-tur
/ˌɪˈndʌktɚ/
inductor is pronounced in-DUHK-tur (/ˌɪˈndʌktɚ/). It has three syllables (in-duc-tor), with the stress on "duc". Inductor refers to a passive electrical component that stores energy in a magnetic field when current passes through it, typically consisting of a coil of wire. It resists changes in current and is characterized by inductance, measured in henries. In engineering contexts, inductors are used in filters, transformers, and signal processing circuits.

"The circuit includes an inductor to smooth out fluctuations in current."
"An LC filter uses an inductor in combination with a capacitor to achieve a specific frequency response."
"The designer selected a high-inductance coil to improve low-frequency performance."
Break it as IN-duc-tor with primary stress on the first syllable. IPA: US /ˈɪn.dək.tɚ/, UK /ˈɪn.dʌk.tə/, AU /ˈɪn.də.k.tɔː/. Start with a short, clipped /ɪ/ in the first syllable, move to a mid-central schwa or /ʌ/ in the second, then a clear, unstressed schwa or rhotic ending. The final syllable reduces to a light /ɚ/ in American speech or /ə/ in non-rhotic UK/AU variants. Mouth positions: lips relaxed, tongue high-mid for /ɪ/; quick, relaxed centralization for /ən/; final consonant cluster /tər/ or /tə/ with minimal release. Audio references: try listening to a loudspeaker pronunciation in technical dictionaries or Forvo entries labeled “inductor.”
Two frequent errors: (1) overpronouncing the second syllable as a full vowel, saying /ˈɪn.dʌk.tær/ instead of a reduced /dək/ or /dək/; (2) merging the final /ər/ into a heavier /ər/ or /ə/ instead of a light /ɚ/ in US or a plain /ə/ in non-rhotic variants. Correction tips: keep the second syllable short with a weak vowel, then release into a compact, unstressed final /tɚ/ or /tə/. Practice with minimal pairs like IN-duc-tor vs IN-duc-tor (reduced) and ensure the /t/ is clearly released before the final schwa. Use a mirror to monitor lip relaxation and jaw position.
US pronunciations typically feature rhoticity with an /ɚ/ ending, e.g., /ˈɪn.dək.tɚ/. UK tends toward a non-rhotic /ˈɪn.dʌk.tə/ or /ˈɪn.dək.tə/ with a shorter, crisper final vowel; Australian often uses /ˈɪn.də.k.tɔː/ with a lengthened final vowel and less rhoticity. The second syllable vowel quality varies: /ə/ or /ʌ/ depending on the speaker and dialect. Across all, the first syllable remains stressed. For practice, listen to regional technical talks and imitate the cadence and vowel lengths closely.
The difficulty stems from the tri-syllabic structure with a reduced middle vowel and a final consonant cluster that blurs into a rhotic or schwa, depending on the dialect. The /d/ followed by a fast /k-/ sequence can create a slip if you don’t separate the /d/ and /k/ clearly, and the final /tər/ or /tə/ requires a short, relaxed release to avoid adding an extra vowel. Focus on centralizing the middle vowel and keeping the final /r/ light in American speech or dropping it in non-rhotic varieties.
The word carries an abrupt onset and a pressed first syllable followed by a mid-vowel in the middle syllable, then a clearly enunciated final consonant cluster. In very careful articulation, emphasize the /n/ immediately after the vowel, keeping the tongue high for /d/ and quickly transitioning to /k/. In practice, you’ll often hear it as a clipped introductory term in specs and white papers, so ensure the first syllable is compact and the rest of the word flows with a steady tempo.

The term inductor derives from the Latin includere, meaning to enclose or to shut in, via the concept of enclosing magnetic energy within a coil. The modern sense emerged in the late 19th and early 20th centuries as electrical engineering matured. It was popularized with the advent of telegraphy and radio, where coils and magnetic cores manipulated electrical energy. The word was adopted into English to describe devices that generate or store magnetic flux; early references often used coil or inductive coil, then consolidated to inductor as the standard term in technical literature. The spelling reflects the noun-forming suffix -tor, akin to other devices that perform a function (decorator, regulator). First documented uses appear in technical handbooks and papers from the 1890s onward, aligning with the rise of wireless telegraphy and electrical machine development. The concept of inductance — the property of producing a magnetic field proportional to current — provided the foundation for the device’s naming. Over time, ‘inductor’ became a fixed term in electronics and remains dominant in circuit theory texts and schematics.
