2 syllables: Ster, oid. Stress on oid.
stur-OYD
/stɚˈɔɪd/
Steroid is pronounced stur-OYD (/stɚˈɔɪd/). It has two syllables (Ster-oid), with the stress on "oid". Steroid is a biological compound, typically a synthetic or naturally occurring hormone, with a core cyclopentanoperhydrophenanthrene ring structure. In common usage, it refers to synthetic anabolic steroids or corticosteroids used medically. The term also appears in sports and pharmacology discussions when describing performance-enhancing substances or anti-inflammatory treatments.

"The athlete’s trainer warned that taking steroids could have serious side effects."
"Doctors prescribed a corticosteroid to reduce inflammation after the surgery."

Pronounce as STIR-oid with primary stress on the first syllable. IPA: US /ˈstɪrɔɪd/, UK /ˈstɪərɔɪd/, AU /ˈstɪərɔɪd/. The first syllable uses a short, lax vowel /ɪ/ followed by an /r/ consonant in US and /ɪə/ in UK/AU, then a clear /ɔɪ/ diphthong in the second syllable. Keep the /dr/ sequence crisp, ending with /d/. Mouth: start with a relaxed jaw, short /ɪ/, roll the tongue to make /r/ or vocalize with an approximant r, then glide into /ɔɪ/ without breaking, finishing with /d/.
Common errors include pronouncing as STEM-id or STEER-oid, or flattening the /r/ into a silent or non-rhotic vowel. Correct by ensuring a clear /r/ after the /t/ and maintaining the /ɔɪ/ diphthong in the second syllable. Practice with minimal pairs: ster-oid vs steer-oid, crystallize the /t/ into a crisp stop before /r/. Use your tongue tip to lightly contact the alveolar ridge for the /t/ and keep the /r/ approximant with a relaxed tongue root.
US: /ˈstɪrɔɪd/ with rhotic /r/. UK/AU: /ˈstɪərɔɪd/ where /ɪə/ or a centering diphthong is used in the first syllable and the /r/ is not pronounced in non-rhotic contexts when not before vowels. In careful speech, UK and AU may insert a subtle schwa-like linking and keep /ɔɪ/. The key differences are rhoticity and the length of the first vowel; US has a tighter /ɪ/ plus /r/; UK/AU feature a longer, rounded /ɪə/ before /ɔɪ/ and may drop rhoticity in some environments.
Two main challenges: 1) The /r/ after the /t/ in American English makes a strong rhotic connector, while UK/AU speakers may link with a faint /ɹ/ or drop rhoticity. 2) The /ɔɪ/ diphthong in the second syllable requires precise movement from /ɔ/ to /ɪ/ while keeping the /d/ closed. Beginners often mispronounce as /ˈsterɔɪd/ or /ˈstɪzɔɪd/. Focus on a clean alveolar stop, then glide smoothly into the /ɔɪ/ with controlled lip rounding.
Steroid features a two-syllable structure with a stressed first syllable and a trailing diphthong /ɔɪ/ before final /d/. Unlike many words, the /r/ is tightly connected to the preceding vowel in US English, producing /ˈstɪr/ rather than /ˈstɪə/ in some casual speech. The combination of a strong alveolar stop and a mid-to-high back diphthong makes it a prototypical example of American rhotic and non-rhotic alternations across dialects.

Steroid comes from a blend of the words steroid (the chemical class) and steroid, ultimately tracing to the early 20th century chemical literature. The root is the steroid nucleus: four fused carbon rings—three six-member rings and one five-member ring—forming the cyclopentanoperhydrophenanthrene skeleton. The term was popularized in the 1930s with the synthesis and isolation of cholesterol-like compounds, and later, the identification of corticosteroids and anabolic steroids expanded its usage. The word likely derives from the Greek stereos (“solid” or “stiff”) and the Latinoid suffix suggesting a resemblance, though the precise lineage is tangled with scientific coinage during the era of rapid steroid chemistry discovery. First known scientific uses appear in mid-20th century pharmacology, aligning with the formal categorization of steroid hormones and synthetic derivatives that could influence metabolism, inflammation, and development. Over time, “steroid” has broadened to cover both beneficial therapeutic agents and substances associated with sport doping, per contemporary medical and cultural discourse.
