Pronounce as /ˈfæl.ə.si/ in US/UK spelling. Stress on the first syllable: FAL-uh-see. The middle syllable is a schwa /ə/, and the final syllable ends with /si/ as in 'see.' Keep the /l/ light and the /l/ clear before the vowel. You can hear it in careful enunciations by dictionaries or pronunciation tools.
Common errors: (1) Over-stressing the second syllable, yielding /ˈfæl.əˈsi/. (2) Turning the middle /ə/ into a full /æ/ or /ɪ/, saying /ˈfæl.æ.si/. (3) Slurring the final /si/ into /siː/ or /si/ with a hard /t/. Correction: keep the second syllable as a reduced schwa /ə/ and end with a crisp /si/; practice interval drills to maintain even timing. Use minimal pairs like fall = /fɔl/ vs fallacy’s /fæl.ə.si/ to keep the rhythm correct.
US and UK both use /ˈfæl.ə.si/, with rhotic influence minimal for /l/ and /r/ not relevant here. Australian tends to be similar but may feature a slightly more centralized /ə/ in the middle and a broader /æ/ realisation in some speakers; syllable timing can be a touch more clipped. The main variation is vowel quality rather than stress. IPA remains /ˈfæl.ə.si/ across regions, but the vowel colour subtly shifts per speaker.
Two challenges: the mid syllable /ə/ is a quick, unstressed schwa that can be forgotten; and the final /si/ needs a crisp consonant before the /i/ vowel. Keep your jaw relaxed for /ə/ and avoid turning the second syllable into /æ/ or /e/. Practice by isolating each syllable, then blending with light emphasis on the first syllable. IPA guidance helps anchor you: /ˈfæl.ə.si/.
A distinctive feature is keeping the first syllable strong with an open front vowel /æ/ while not letting the second syllable become overly prominent. The balance between the heavy first syllable and the light middle syllable is key for natural-sounding speech. You’ll hear native speakers make the middle /ə/ almost disappear in rapid speech; you should practice maintaining the schwa clearly in careful speech for accuracy.

Fallacy comes from the Latin fallacia, meaning deception, trick, or fraud. Fallacia itself derives from fallere, to deceive or to be deceptive. In classical rhetoric, a fallacia was a deceptive argument or rhetorical trick intended to mislead the audience. The term entered English through philosophical and rhetorical treatises in the 16th century, aligning with epistemology and logic discussions. Over time, fallacy expanded beyond deliberate fraud to include any reasoning error or misleading pattern—circular arguments, non sequiturs, or appeals to emotion. The word structure mirrors Latin roots: fallere (to deceive) + -acy (state or quality). The concept matured with the rise of formal logic and critical thinking curricula in the 19th and 20th centuries, where fallacies are catalogued in lists and used as teaching tools for argument analysis. First known English uses date from early modern scholastic texts, but the idea of a deceptive error in reasoning is ancient, traceable to Aristotle’s informal canons of argument and later syllogistic refinements. In contemporary usage, “fallacy” is ubiquitous in debates, journalism, and policy analysis as a term to label reasoning that seems plausible but fails to meet rigorous logical standards.
