Pronounce as PO-ten-cy, with primary stress on the first syllable: /ˈpoʊ.tən.si/. Start with a clear /poʊ/ as in 'poe,' then a lighter /tən/ cluster, and end with /si/. The middle syllable is unstressed and reduced to a schwa-like /ə/ in careful speech. Mouth start wide for /poʊ/, tongue high-mid for /oʊ/, then a relaxed, brief /t/ + /ən/ before a final /si/.
Common errors: 1) Placing secondary stress on the second syllable (po-TEN-si) which shifts rhythm and quality; avoid by keeping primary stress on the first syllable. 2) Flattening the /t/ into a quick flap like 'pot-nee' instead of a clear /t/ followed by a reduced /ən/. 3) Using a tense /i/ at the end instead of a clear /si/; aim for final /si/ with a light vowel. Practice with slow, deliberate syllable transitions.
Across US/UK/AU, the primary stress remains on the first syllable. US and UK rhymes align with /ˈpoʊ.tən.si/. In some Australian speech, the /oʊ/ vowel can be realized closer to /əʊ/ or may be slightly longer, and vowel length can be a touch more variable. The final /si/ tends toward a clear, unvoiced /si/ but may sound a touch closer to /siː/ in rapid speech. Overall, differences are subtle and revolve mainly around vowel quality and rhythm.
The difficulty comes from the sequence /poʊ.tən.si/: a stressed first syllable, a reduced mid syllable, and a final /si/ cluster. The mid syllable has a weak vowel that can blur, so you may inadvertently say /poʊtɛnsɪ/ or /poʊtənsi/ with weak clarity. Focus on keeping the /t/ clean, ensuring the /ən/ passes quickly into /si/ without a full vowel elongation. Training with slow, exaggerated segments helps stabilize the rhythm.
The word contains a brief, unstressed central schwa in the middle syllable (/ˈpoʊ.tən.si/). The /ən/ cluster requires a quick, relaxed vowel that doesn’t fully vocalize. You’ll notice a light, almost whispered mid vowel before the final /si/. Mastering this subtle reduction prevents the word from sounding over-articulated and ensures natural rhythm in connected speech.

Potency derives from the Latin potentia, meaning ‘power, ability, potential,’ from potens, potent-, ‘powerful, able.’ The word entered English viaOld French potenté and Middle English, maintaining its sense of power or capability. Early uses in the 15th–16th centuries often referred to physical strength or the power of a person or agent. By the 17th–18th centuries, potency broadened to describe chemical strength, medicinal efficacy, and pharmacological activity, aligning with scientific discourse popularizing the term. In pharmacology, potency denotes the dose required to achieve a given effect, later refined into a precise measure of a drug’s biological activity. Today, potency is a standard term across science, medicine, and law, retaining its core meaning of capacity or effectiveness while appearing in more specialized contexts (e.g., potency of a toxin, potency of a fragrance). First known use in English traces to the late Middle English period, with Latin roots tracing further back to potent-, ‘able, powerful.’
