/ɹiˌkɑmbɪˈneɪʃən/
Say it backRecombination refers to the process of combining genetic material from different sources to form new allele combinations. It is a key mechanism in genetics that increases variation in populations. The term may also be used more broadly to describe the rearrangement of components in a system to form new configurations.
"The study focused on the rate of recombination across the chromosome."
"During meiosis, recombination contributes to genetic diversity in offspring."
"Scientists engineered a recombination event to create a novel protein complex."
Pronounce it as /ˌriː.kɒm.bɪˈneɪ.ʃən/. The primary stress lands on the fourth syllable -ne- in -neɪ.tion, so it sounds like re-com-bin-A-tion, with a light secondary stress on the first syllable and a clear, crisp final schwa in -tion. Start with /riː/ (long ee), then /ˈkɒm/ (kɒm like 'comb'), /bɪ/ (short i), /ˈneɪ/ (long aɪ? actually /neɪ/ as in 'nape' with a long eɪ sound), and finish with /ʃən/ (shun). Audio references: you can compare with Pronounce or Forvo entries; listening while mouthing helps.
Common errors: misplacing the primary stress on the wrong syllable (say re-COM-bin-ation or re-com-bin-A-tion). Another is pronouncing -neɪ- as /naɪ/ or /neɪən/; keep /neɪ/ as in 'nate' with a long a. Also, rushing the sequence can blur the /ˈkɒm/ cluster and the /bɪ/ syllable; clearly articulate the /mb/ in /ˈkɒm.bɪ/ and avoid a silent or swallowed /m/. Practice slowly to lock in the correct stress and consonant clusters.
US tends to speed up the overall syllable rhythm with less reduction in the middle; the /ɒ/ in /ˈkɒm/ is more open. UK preserves a crisper /ɔː/ in some speakers, but generally retains /ˈkɒm/. AU often merges vowels more, with slightly wider mouth opening for /ɒ/ and a tendency toward a flatter intonation. Across all, the sequence re-kɒ-m-bɪ-ˈneɪ-ʃən remains, but vowel quality and syllable length shift subtly; listen for rhotics in US vs non-rhotic UK accents.
The difficulty lies in the multi-syllabic rhythm and the sequence /ˌriː.kɒm.bɪˈneɪ.ʃən/ with a voiced /mb/ cluster and a stressed /neɪ/ syllable. The /mb/ combination requires a brief nasal release before a bilabial stop, and the final -tion /ʃən/ reduces slightly in casual speech, which can blur the ending. Focus on maintaining the /m/ before /b/, keep the /neɪ/ clear, and avoid merging into /neɪn/ or /nɜː/. IPA cues help you segment the word.
A distinctive feature is the /ˈneɪ.ʃən/ ending portion where the /eɪ/ forms a long vowel before the /ʃən/ suffix; many learners reduce /ɪ/ before 比, but here you should sustain /neɪ/ clearly. Another unique aspect is the /mb/ cluster at the second syllable; ensuring an audible bilabial nasal release before the /k/ is essential to avoid blending into /kɔm/ or /mɔm/.
🗣️ Voice search tip: These questions are optimized for voice search. Try asking your voice assistant any of these questions about "recombination"!
Recombination derives from the prefix re- (again) + combination (the act of combining) with the insertion of the root part recombin- from Latin recombinare, meaning “to unite again.” The Latin recombinare itself is formed from re- (again, back) + combine (to bring together) with the -atio/ -ion noun formation. The sense in genetics crystallized in the 20th century, influenced by the broader scientific vocabulary of chemistry and biology, where “recombination” described the reuniting of genetic segments after breakage. First known use in English appears in mid-20th century scientific literature as understanding of genetic exchange mechanisms matured. Over time, the term has expanded into algorithmic and computational contexts where separate components are recombined to generate new solutions. The enduring core idea: taking existing parts and reshaping their arrangement to yield novel configurations. In modern usage, you’ll see it in contexts ranging from molecular biology to computer science, with specificity to the type of recombination (homologous, site-specific, or algorithmic).
