3 syllables: Ab, scis, ic. Stress on scis.
ab-SIS-ik
/æbˈsɪsɪk/
Abscisic is pronounced ab-SIS-ik (/æbˈsɪsɪk/). It has three syllables (Ab-scis-ic), with the stress on "scis". Abscisic is an adjective relating to abscisic acid or to branches of plants that have shed leaves; in biology this term often describes molecules or processes tied to seed dormancy, stress responses, or growth inhibition. The word conveys scientific exactness and is used primarily in technical or academic contexts, especially botany and biochemistry. It is pronounced with emphasis on the second syllable: ab-SCI-sic.

"The abscisic acid pathway regulates seed dormancy in many flowering plants."
"Researchers study abscisic acid levels under drought stress."
"The abscisic-like response was observed in the treated plant samples."
You say ab-SCI-sic, with the primary stress on SCI. Phonetically: /abˈsaɪsɪk/. Start with an open front short A, then a secondary sound for b as a quick bilabial, then SCI as a long high-diphthong /ˈsaɪ/ followed by /sɪk/. Tip: keep the /s/ crisp and finish with a light /k/. Audio references: YouGlish and Pronounce offer examples for this exact word.
Common errors: misplacing stress (saying ab-SIS-ic), mispronouncing the SCI as /si/ or /saɪ/ in one syllable, and flattening the final -ic. Correction: ensure the /ˈsaɪ/ diphthong carries the primary stress and the second syllable has a reduced vowel, finishing clearly with /k/. Practice saying “ab” quickly, then “SCI” with a strong, forward tongue position, then a crisp /k/. Practicing in a phrase like ‘abscisic acid’ helps cement the rhythm.
In US English, you’ll hear /æbˈsaɪsɪk/ with a lax initial /æ/ and rhotic pronunciation of following vowels. UK English tends to use a slightly tenser /æ/ with broader /ɪ/ in the second syllable and more fronted /sɪk/. Australian pronunciation generally aligns with UK/US patterns but can feature a more centralized second syllable vowels. Focus on the /ˈsaɪ/ diphthong; rhoticity affects surrounding vowels subtly in connected speech.
The difficulty lies in the three-syllable rhythm with a stressed mid syllable and a tricky /ˈsaɪ/ diphthong sandwiched between /b/ and /s/. The /s/ before -ic is a crisp, voiceless consonant that can blur when spoken quickly, and the final /k/ must be released cleanly to avoid sounding like /sɪk/ or /sɪkk/. Mastering the sequence ab-SCI-sic requires careful articulation of the diphthong and final stop. IPA helps you see the exact sounds.
A distinctive feature is keeping the second syllable’s diphthong /aɪ/ clearly separated from the preceding /b/ and following /s/ cluster, ensuring an audible pause between /b/ and /ˈsaɪ/. This makes ab-SCI-sic feel almost like two strong syllables packed with a tight /s/ start to the third syllable. Practicing with a slow pace emphasizes the contrast between /b/ and /ˈsaɪ/.

Abscisic derives from Latin abscisus ‘cut off, separated,’ from ab- ‘away from’ + scissus ‘cut’ (past participle of scindo ‘to cut’). The botanical use emerged from early 20th century biochemistry, where scientists described substances related to the abscission process—leaf drop—and broader plant hormone functions. Although the root abscis- originally signals detachment, the term evolved to denote a specific class of hormones (abscisic acid, ABA) that controls seed dormancy and stress responses rather than mere detachment. The first known use in scientific literature appeared in the 1940s–1950s as researchers described compounds involved in abscission and dormancy signaling. Over time, the term narrowed to designate ABA-related processes and molecules in plant physiology, becoming a standard adjective in plant science, physiology, and biochemistry. The modern usage often appears in contexts like “abscisic acid signaling” and “abscisic acid-responsive genes.”
