antitoxin is pronounced an-tee-TAHK-suhn (/ˌæntiˈtɑksən/). It has four syllables (an-ti-tox-in), with the stress on "tox". An antidote against a specific toxin, often referring to a preparation of antibodies or enzymes used to neutralize harmful substances. In pharmacology, antitoxins are agents that counteract toxins produced by organisms or pathogens, typically administered to treat exposure. The term combines the prefix anti-, meaning against, with toxin, meaning a poisonous substance.

"The doctor administered an antitoxin to neutralize the venom."
"Researchers studied antitoxins to develop better antivenoms."
"The patient received antitoxin therapy after a suspected toxin exposure."
Pronounce as an-ti-TOX-in with stress on the second syllable: [ˌæntɪˈtɒksɪn] in UK and [ænˌtaɪˈtɒksɪn] US; in American practice you’ll commonly hear IPA /ˌæntaɪˈtɒk sɪn/ depending on regional variation. Start with /ˈænt/ then /ɪ/ or /i/ leading into /ˈtɒks/ followed by /ɪn/. Mouth positions: lip-spread for /æ/, jaw drops for /ænt/, tongue high-mid for /ɪ/ in the second syllable, and the /tɒk/ syllable uses a hard 't' followed by a short 'k' release. Listen for the secondary stress on the middle-to-late syllable and ensure the final /n/ is clearly pronounced.
Common mistakes: over- or under-emphasizing the second syllable causing mis-stress, and mispronouncing the /tɒk/ cluster as /tɒksɪ/ with an incorrect vowel. Correction tips: place primary stress on the third syllable: an-ti-TOX-in; keep the /t/ and /k/ tightly sequenced with a short /ɒ/; practice the sequence /ˈtɒks/ with a crisp release. Use minimal pairs like toxin vs antitoxin to train the /æntɪ/ vs /ænti/ onset and ensure the /t/ is unaspirated in the middle.
In US English the second syllable carries primary stress: an-ti-TOX-in, with rhotic influence on vowels and clear /t/ release before /ɒ/. UK English tends to a slightly reduced vowel in the first syllable and a perhaps stronger /ɔː/ in /ɒ/ depending on region; non-rhotic tendencies may soften the /r/ and lengthen the vowel. Australian English often features a broader /ɒ/ and a less pronounced /ɪ/ in the first syllable, with a stable /t/ and final /n/. Overall, rhythm is syllable-timed vs stress-timed, and vowel quality shifts are most apparent in /æ/ vs /æɪ/ or /ɒ/.
The difficulty centers on the multi-syllabic structure with a mid-word /tɪ/ or /taɪ/ variation and the /tɒks/ cluster, requiring precise timing between syllables. The middle syllable carries a strong consonant cluster /tɒk/ that can blur if you’re not separating the release. Also, global accents vary in the vowel: /æ/ in US vs /ɑː/ in UK contexts. Focus on accurate syllable division, deliberate alveolar stop release, and keeping the /ɒ/ vowel clear before the /k/.
Does antitoxin ever sound like 'anti-toxin' with a soft 't' between 'anti' and 'toxin' in rapid speech? In careful speech, the boundary is clear: an-ti-TOX-in with the 't' held briefly, but in fast speech you may hear a slight assimilation, e.g., [ˌæntɪˈtɒksɪn] with a crisp /t/ before the /ɒ/. Maintain separate syllable boundaries to avoid fusion, especially in medical dictation.

Antitoxin derives from the combination of two Old French/Latin roots: anti- meaning against and toxin which itself comes from Greek toxinē (toxin). The term toxin traces to Latin toxinum from Greek toxon, meaning bow or poison, originally referencing archery toxins then broader poisons. The prefix anti- is from Greek anti- meaning against. The first known uses date back to the late 19th to early 20th centuries in medical literature, when immunology and serology were expanding to counteract bacterial and venom-derived poisons. Early antitoxins were sera produced by immunizing animals to generate antibodies, later refined through human serum therapy and monoclonal antibody technologies. Over time, antitoxins became a general pharmacological class describing preparations that neutralize toxins, with specific formulations for tetanus, diphtheria, botulinum, snake venoms, and other toxin-mediated diseases. The term has evolved to denote any biological or enzymatic agent that neutralizes a toxin, not just immune sera, reflecting advances in biotechnology and recombinant antibody therapies.
