/ˌriːˌsɜːrkjəˈleɪʃən/
recirculation is pronounced ree-surr-kyuh-LAY-shuhn (/ˌriːˌsɜːrkjəˈleɪʃən/). It has five syllables (re-cir-cu-la-tion), with the stress on "tion". Recirculation refers to the process of circulating something, such as air or liquid, again within a closed system or environment. It involves pulling the medium back into a loop for processing or reuse, often to conserve energy or resources. The term is commonly used in engineering, environmental science, and medical contexts to describe reintroduction of the medium without external exchange.

"The building's HVAC system uses recirculation to maintain temperature while minimizing energy use."
"In the experiment, the reactor achieved higher efficiency after implementing recirculation of the reactants."
"Medical devices often rely on recirculation loops to filter and reuse saline solution."
Break it as re-cir- cu-la-tion with primary stress on the third syllable: re- /rɪ/; ci- /ˌsɜr/; r- cu- /ˌkjuː/; la- /lə/; tion /ˈʃən/ in US. A natural rhythm is /ˌriː-sɜːr-kjuː-ləˈreɪ-ʃən/ depending on accent. In IPA: US: /ˌriːsɜːrˌkjʊləˈreɪʃən/; UK: /ˌriːsɜːkjʊləˈreɪʃən/; AU: /ˌriːsɜːkjʊləˈreɪʃən/.
Mistake 1: stressing the wrong syllable (stress on 'la') — correct to place primary stress on the 'ca' or 'cu-la-tion' part as /ˌriː-sɜːrk-juː-lə-ˈreɪ-ʃən/. Mistake 2: blending 'cir' and 'cu' into a single cluster or mispronouncing 'cu' as 'cu' in 'cute' rather than 'kyu' /kjʊ/. Correct to ensure 'cir-cu' forms /ˈsɜːr.kjuː/ with a clear /kjuː/ sequence. Mistake 3: pronouncing 'tion' as 'shun' with heavy t; better pronounce 'tion' as /ʃən/ in many accents or /tən/ in careful speech.
US tends to reduce the first vowel in the second syllable: /ˌriːsɜːrˌkjʊləˈreɪʃən/ with rhotic /r/. UK often uses a non-rhotic rhythm in rapid speech and may raise the /ɜː/ to /ɜː/ or /ə/; UK: /ˌriːsɜː.kjuː.ləˈreɪ.ʃən/. AU mirrors US rhotics more, with a longer /iː/ in the initial syllable; AU: /ˌriːˌsɜː.kjuː.ləˈreɪʃn̩/ depending on speaker. The main variegation is rhotics and vowel quality in the second syllable, plus smoothing of /kj/ into /kju/.
Two main challenges: the multi-syllabic structure with four or five phonetic beats and the cluster /kju/ after /sɜr/; keeping stress position steady while delivering the /ˈr/ sequence. Also the final -tion can be ambiguous: /ʃən/ or /ən/. Concentrate on maintaining a clear /kjʊ/ sequence and the final schwa-like /ə/ before the /ʃən/ segment in many accents.
Note the syllable boundary after 'cir' and before 'cu': recir- cu-lation divides cleanly as /ˌriː-sɜːrˈkjʊ-ləˈreɪʃən/ in careful enunciation; most speakers connect 'cir' and 'cu' with a light /r/ or /ɹ/ glide. Paying attention to the /kj/ sequence helps avoid rushing the 'u' into the 'l'. This careful segmentation improves clarity in technical speech.

US: rhotic pressure and clearer /r/; longer vowels in stressed syllables. UK: non-rhotic tendency, less rhoticity in rapid speech, /ɜː/ quality; AU: more US-like rhotics with clear /r/ and similar vowel timing. IPA anchors: US /ˌriːsɜːrˌkjʊləˈreɪʃən/; UK /ˌriːsɜː.kjuː.ləˈreɪʃən/; AU /ˌriːsɜː.kjuː.ləˈreɪʃən/. Focus on /sɜːr/ or /sɜː/ and /kj/ for consistency.
Recirculation is formed from the prefix re- (Latin: 'again, back') + circul- (Latin root from circulus meaning 'little circle' or 'circle') + -ation (Latin-derived noun suffix). The word follows a productive English pattern for technical processes: a base noun circulus evolves into circulation, then the prefix re- attaches to denote repetition or return. The earliest sense of circulatio in Latin referred to a turning around or movement in a circle; by medieval Latin it took on general mechanical senses related to conveyance in a loop. In English, circulation appeared in the 15th–16th centuries in medical and anatomical contexts (blood circulating), later expanding to hydraulics, ventilation, and broader engineering usage. Recirculation as a compound noun or verb meaning 'to circulate again within a closed system' emerged in the 20th century with the rise of complex environmental control systems, closed-loop manufacturing, and modern HVAC terminology. The word captures a modern concern for resource efficiency: reusing medium (air, liquid, or gas) rather than discharging it, and is now common in sustainability discourse, medical device design, and process engineering.
