recursion is pronounced rik-URR-zhuhn (/ɹɪˈkɜːrʒən/). It has three syllables (re-cur-sion), with the stress on "cur". Recursion refers to a process in which a function, idea, or problem refers to itself, often within a smaller instance of the same task. It is a common concept in mathematics, computer science, and linguistics, enabling solutions via repeated self-application until reaching a base case. The term also describes self-referential patterns in language and art.

"In programming, recursion is used to compute factorials by calling the function within itself until it reaches the base case."
"The proof relied on recursion, applying the same reasoning to progressively smaller subproblems."
"In fractal art, recursion creates infinitely complex patterns by repeating a simple motif at different scales."
Pronounce it as /rɪˈkɜːrʒən/ in US/UK, with US typically /rɪˈkɜrʒən/. Syllable stress falls on the second syllable. Start with a short, lax /rɪ/; the middle is a stressed /ˈkɜːr/ (US) or /ˈkɜː/ (UK), followed by /ʒən/ or /ʒən/ depending on accent. Tip: keep the /r/ light, avoid a heavy trill, and ensure the /ʒ/ is voiced clearly.
Common mistakes: misplacing the stress on the first syllable (re-), and mispronouncing the middle as /kɜrn/ or /kɛr/ instead of /kɜːr/. Another pitfall is pronouncing the final /ən/ as /ən/ with an unstressed schwa that bleeds into the preceding /r/; ensure the final /ən/ has a lighter, clipped vowel: /ʒən/. Correct by practicing the clear /ˈkɜːr/ and crisp /ʒən/.
US: /rɪˈkɜrʒən/ with rhotic /r/ and a tighter /ɜr/; UK: /rɪˈkɜːʃən/ with longer /ɜː/ and often a lighter /ʒ/; AU: /rɪˈkɜːʃən/ similar to UK but with Australian vowel color, often less rounded /ɜː/. The key is the middle vowel length and the final /ən/ realization, which can be a schwa-like /ən/ in US and a more central vowel in AU/UK.
The challenge lies in the multi-syllabic structure with a mid-stressed syllable and the cluster /kr/ followed by the retroflex /ʃ/ (represented by /ʒ/). The sequence /kɜr/ can be mis-timed, and the /ʒ/ sound is less common for some speakers. Additionally, the final -tion tends to reduce to /ən/ or /ən/, requiring careful vowel reduction. Focus on isolating /ˈkɜːr/ and a crisp /ʒən/.
A distinctive feature is the /ʒ/ sound in the middle syllable, which is less common in everyday English for non-technical terms. It’s easy to mispronounce as /ʃ/ (sh) or /tʃ/ (ch). Ensure you voice the /ʒ/ as in measure, with the tongue relaxed and airflow steady. This sound sits between /s/ and /z/ in placement and requires careful tongue blade positioning.

US: rhotic /ɹ/ with a tighter /ɜ˞/ in /ɜr/; UK: non-rhotic or weak rhotics, longer /ɜː/; AU: rhotic but softer, vowel shifts toward /ɜː/. Vowel quality: US often closer to /ɪ/ in the initial syllable, while UK/AU lean toward /ɪ/ or /ɪə/ depending on speaker. Consonants: /ʒ/ remains consistent; ensure voicing and sibilant harmony across syllables. IPA references: /rɪˈkɜːrʒən/ (US), /rɪˈkɜːʃən/ (UK), /rɪˈkɜːʃən/ (AU).
Recursion comes from the Latin verb recurrere, meaning to run back or return. The root rit- (to return) pairs with re- (again) and cur- (to run). The term was first used in mathematical and logical contexts in the 19th century as mathematicians and logicians formalized self-referential definitions. Early uses appeared in discussions of recursive functions and the concept of defining objects in terms of themselves. In computer science, recursion became a foundational idea in the mid-20th century with the rise of formal language theory and programming languages, where a function can call itself. The word’s sense broadened to include self-similar patterns in nature and art, as seen in recursive sequences and fractals. Today, recursion is a standard term across disciplines, often accompanied by discussions of base cases, termination, and stack behavior in computing. The pronunciation remains consistent: /rɪˈkɜːrʒən/ in US and UK usage, with minor regional vowel differences. First known written uses include mathematical recursion in the 1800s and computer science references in the 1960s.
