dichlorodiphenyltrichloroethane is pronounced deye-KLAW-roh-deye-fee-nil-treye-klaw-roh-ee-thayn (/daɪˈklɔɹoʊdaɪfiːnɪltraɪklɔɹoʊiːθeɪn/). It has seven syllables (di-chloro-di-phenyl-tri-chloro-ethane), with the stress on "phenyl". A long organic compound renowned as a synthetic insecticide, commonly known as DDT. It consists of multiple aromatic rings substituted with chlorine atoms, and it has a history of widespread agricultural use and environmental controversy. The term refers specifically to the chemical substance, not its applications or regulations, and is pronounced in single stretch due to its stable, recognized name.

"The chemical name dichlorodiphenyltrichloroethane is rarely spoken aloud, but researchers write it in full on the order forms."
"Some older environmental studies mention the persistence of dichlorodiphenyltrichloroethane in soil and water."
"Dichlorodiphenyltrichloroethane was globally regulated after evidence of bioaccumulation emerged."
Pronounce it as: di-chlo-ro-dip-he-nyl-tri-chlo-ro-eth-ane. Stress falls on the ‘phe’ of diphenyl? or the ‘thane’? In standard practice, stress is broadly on the central-heavy syllable: /ˌdaɪ.kloʊr.o.dɪˈfɛnˌaɪlˌtraɪ.kloʊˌroʊˈeθ.eɪn/ (approx US). Break it into 4-5 clinical chunks: di- chloro- di- phenyl- tri- chloro- eth- ane. You’ll hear the strongest emphasis on the syllables around ‘phenyl’ and ‘ethane’ in many scientific readings. Reference audio: Forvo and YouGlish will provide native pronunciations; listen to several speakers to align with your preferred scientific diction.
Common errors include misplacing the many ‘chloro’ sequences, e.g., saying ‘dichloro-diphenyl-trichloroethane’ with even stress and ignoring the liquid, flowing rhythm; mispronouncing ‘phenyl’ as ‘phenal’; and rushing long consonant clusters like -trichloro-. Correction: segment the word in natural chunks (di-chloro-diphenyl-trichloro-ethane), clearly articulate each -clo- syllable, and slow the transitions between the multiple -chloro- and -ethane segments.
In US, you’ll often hear a rhotic pronunciation with r-colored vowels and slightly lighter final -ane; UK may exhibit non-rhoticity, with more clipped final vowels; Australian tends to a broad vowel quality and a clearer vowel duration in long syllables. The sequence -ethane is a key anchor; ensure you differentiate -ane (/eɪn/ or /ən/ in fast speech) from -an. Listening to regional readings on pronunciation resources will help you map the exact vowel quality differences.
It combines many repeated 'chloro' clusters and long phonetic sequences, with 9+ syllables, multiple triplet consonant clusters (-trichloro-) and sensitive vowels, making it easy to swallow syllables, mis-stress, or slur the chain. Focus on chunking, maintain rhythm, and practice slow-to-normal tempo until smooth.
The word contains three consecutive 'chloro' morphs in the long form: dichloro-diphenyl-trichloroethane. Be mindful of the ‘-thane’ ending; pronounce as a clean -theɪn / -θeɪn with a soft nasal onset before the final vowels, avoiding a heavy consonant cluster muddle.

The word is a concatenation of multiple Greek-derived and Latin elements describing its structure and chlorination pattern. ‘Dichloro’ signals two chlorine substituents, ‘diphenyl’ refers to two phenyl rings, ‘trichloro’ indicates three additional chlorines, and ‘ethane’ denotes the two-carbon backbone. The term arose in the mid-20th century as chemists named a family of chlorinated hydrocarbons with persistent, lipophilic traits. First synthesized in the 1870s and thoroughly characterized in the 1930s by Paul Müller’s team, its practical insecticidal value led to broad adoption in the 1940s. The name crystallized to a single, standardized designation as international regulatory discussions intensified from the 1960s onward, with DDT entering common scientific parlance and затем, after environmental concerns, guiding policy and nomenclature across industries and languages worldwide.
