/saɪkləʊfɒsˈfəmaɪd/
cyclophosphamide is pronounced seye-kloh-fos-FUH-meyed (/saɪkləʊfɒsˈfəmaɪd/). It has five syllables (cy-clo-phos-pha-mide), with the stress on "pha". Cyclophosphamide is a chemotherapy agent that alkylates DNA, disrupting cancer cell replication. It is a prodrug activated in the liver and used for various hematologic and solid tumors. The term combines cyclo- (ring) and phosphamide (phosphorus-nitrogen compound) roots, reflecting its chemical structure.

"The patient received cyclophosphamide as part of the regimen for lymphoma."
"Researchers investigated cyclophosphamide dosing to minimize urotoxicity."
"Cyclophosphamide is typically administered with hydration and mesna to protect the bladder."
Pronounce as /ˌsaɪkloʊfəsˈmædaɪd/ in US, with primary stress on the 'ma mide' portion; in UK, /ˌsaɪkləʊˈfɒsˌmædaɪd/. Break it into syllables: cy- CLO- phos- pham- ide. Start with a light 'cy-' then a strong 'clo-' or 'klo', then 'fos' or 'foss', followed by 'maide'.
Common errors: 1) Dropping or misplacing the -pho- as in 'cyclophasmide'; 2) Mis-stressing the wrong syllable (placing stress on 'pham' instead of 'fos-ma'); 3) Slurring the 'ph' sound into a simple 'f' or 'ph' into 'v'. Correction: keep 'pho' as /foʊ/ or /fɒ/ with a clear /f/ and avoid 'ph' confusion; place primary stress on the 'ma' in -mide, i.e., cy-klo-fo-s-MA-id.
US: /ˌsaɪkoʊfəsˈmæmˌaɪd/; UK: /ˌsaɪkləʊˈfɒsˌmædaɪd/, AU: /ˌsaɪkləˈfɒsˌmædaɪd/. Rhoticity affects the 'r' absence in non-rhotic accents; vowel quality shifts: US tends to /oʊ/ in 'cyc' and /æ/ in 'maid', UK uses more open /ɒ/ for 'phos' and a clipped /dəɪd/ for 'ide'.
Because it combines a long multisyllabic sequence with rare consonant cluster: 'cyclo-' followed by 'phos-' and a silent-like 'ph' feel, plus the final '-mide' ending that can become /maɪd/ or /maɪd/. The body of the word has two stressed segments and a ligature between 'ph' and 'am', requiring precise articulation of /f/ vs /ph/ (pronounced /f/), and maintaining distinct syllable boundaries so the 'phos' isn't swallowed.
The 'ph' sequence is not an aspirated 'ph' as in 'phone' but represents an /f/ sound in this word, and the 'ide' ending can be reduced in rapid speech. The 'phos' cluster requires a clear 'f' and the 'maide' ending demands a crisp /maɪd/ rather than a lax ending. Emphasis is typically on the 'ma' of '-mide', not earlier syllables, in many clinical readings.

Cyclophosphamide derives from Greek cyclo- (κύκλος, circle) meaning a ring structure, and the phosphamide part from phosphor- (phosphorus) and -amide (chemical group). The name reflects its chemical composition: a cyclic amide with a phosphoramide linkage. The term entered medical chemistry in the mid-20th century as researchers characterized nitrogen mustard analogs with modified rings. It was first described in literature as a synthetic alkylating agent capable of forming cross-links in DNA, thereby inhibiting replication. Over decades, cyclophosphamide became a cornerstone in chemotherapy regimens (e.g., CHOP, COP) and also studied for immunomodulation in autoimmune diseases. The word’s syllables map to its molecular biology: cyclo- (cyclic), phylo- not directly, but -phosphamide signals phosphorus-containing amide groups, and the full compound name is treated as a single lexical unit in medical contexts.
