/ˈsikwənsɪŋ/
Say it backSequencing refers to arranging things in a specific order or succession, or the process of determining that order. In biology, it denotes determining the sequence of DNA or RNA bases. It conveys a procedural or logical progression, often used in data analysis, manufacturing, and computational contexts to establish a stepwise arrangement or pattern.
"The sequencing of the genome revealed how the genes are organized."
"We reviewed the sequencing steps to ensure the project proceeded in the correct order."
"In cinema, sequencing of shots helps create a coherent narrative flow."
Pronounced sə-KWEN-siŋ, with stress on the second syllable. The initial reduced syllable 'se-' sounds like /sə/ and the key stress falls on the 'KWEN' part: /ˈKWEN/ within the word, followed by /siŋ/. Overall IPA: US/UK/AU: səˈkwɛn.sɪŋ. Place your tongue high in the back of the mouth for the /kw/ cluster and finish with a nasal /ŋ/.
Common mistakes include emphasizing the first syllable (se-), producing /ˈsiːkwən/ or misplacing the /kw/ cluster. Some speakers insert an extra vowel between /k/ and /w/, saying /ˌsiːˈkwɛn.sɪŋ/ or /sɪˈkwɛn.sɪŋ/ instead of /ˌsəˈkwɛn.sɪŋ/. Another frequent error is finalizing with a hard 'g' instead of the velar nasal /ŋ/. Correction: keep the unstressed initial schwa /ə/ (or /sə/) then tightly cluster /kw/ followed by /ɛn/ and finish with /sɪŋ/.
In US, UK, and AU, the second syllable /KWEN/ remains stressed, but rhoticity affects preceding vowels: US often has a rhotic schwa /ər/ tendencies in connected speech, UK/AU are non-rhotic in careful speech, so you may hear /səˈkwɛn.sɪŋ/ more distinctly without linking r. Vowel quality of /e/ might be closer to /ɛ/ in some UK varieties and /eɪ/ in certain dialects, but standard pronunciations converge on /əˈkwɛn.sɪŋ/. The /ŋ/ finale is consistently velar nasal.
The difficulty lies in the consonant cluster /kw/ immediately after the unstressed syllable and the syllable break pattern with secondary stress on /KWEN/. The /sə/ leading schwa can blend with nearby vowels in rapid speech, and the final /sɪŋ/ requires precise tongue rear placement for the nasal /ŋ/. Practicing the /kw/ cluster and the final nasal in sequence helps prevent vowel epenthesis and mis-timing of syllable boundaries.
Does the word 'sequencing' ever reduce to 'sequencin' in fast speech, and how should you maintain full syllables? In careful speech you can retain /səˈkwɛn.sɪŋ/ with full vowel length in the first syllable and the /sɪŋ/ ending. In casual contexts, you might hear a reduced /səˈkwɛn.sɪŋ/ with a subtle vowel reduction in the second syllable, but the final /ŋ/ should remain clear to avoid ambiguity.

The word sequencing originates from the noun sequence, which comes from late Latin sequens, -entis, meaning 'following' or 'coming after.' The Latin root sequ- derives from the verb sequi, meaning 'to follow.' The English noun sequence appeared in the 14th century, initially in mathematical and logical contexts, then expanding to music, linguistics, and later molecular biology as scientists described ordered series of nucleotides or amino acids. The sense of organizing items by order strengthened with the rise of sequencing technologies in the 20th century, especially in genetics and data processing. By the late 20th century, the term was entrenched in biological sciences to describe determining the exact order of bases in DNA/RNA, and in computing to designate ordered data processing. First known use in English literature traces to discussions of mathematics and logic, with modern specialized usage spreading in biology and information technology as sequencing became a core operation in genomics and sequencing pipelines.
