3 syllables: Ab, scis, sa. Stress on scis.
uhb-SIS-uh
/əbˈsɪsə/
Abscissa is pronounced uhb-SIS-uh (/əbˈsɪsə/). It has three syllables (Ab-scis-sa), with the stress on "scis". Abscissa is a mathematical term referring to the x-coordinate in a two-dimensional Cartesian plane. It denotes the horizontal distance of a point from the origin, typically measured along the x-axis. In broader use, it can also mean a perpendicular distance, or a labeled axis in graphs and coordinates.

"The point (3, 7) has an abscissa of 3."
"Plot the abscissa on the horizontal axis before you note the ordinate."
"In the spreadsheet, the abscissa values increase from left to right."
Pronounce as ab-SIK-suh with the primary stress on the second syllable: /ˈæbˌsɪk.sə/. Make sure the /b/ is clearly released, the /s/ is crisp after the -b-, and the final -a is a light schwa. Listen for a concise, brisk rhythm: two strong beats followed by a light ending syllable. If you need an audio reference, you can check reputable dictionaries or pronunciation platforms and match the /ˈæbˌsɪk.sə/ pattern.
Common errors include stressing the first syllable (ai-BSIK-suh) instead of the second, mispronouncing the /s/ as /z/, or flattening the final -a into a full vowel like /eɪ/ instead of a neutral schwa. To correct: keep primary stress on the second syllable, clearly articulate the /ks/ sequence as /k s/ rather than a single /ks/ blend, and finish with a short, relaxed /ə/ rather than a pronounced vowel. Practicing with minimal pairs like /ˈæbˌsɪk.sə/ vs /ˈæbˌzɪk.sə/ can help train your ear.
US/UK/AU generally share /ˈæbˌsɪk.sə/, with the main differences being vowel quality and rhoticity in connected speech. In rhotic accents like US, the /r/ is not present in this word itself but influences surrounding vowels in rapid speech, while UK and AU tend to have a slightly crisper /sɪk/ and a less pronounced vowel in unstressed syllables. The primary stress remains on the second syllable, but some speakers may give a bit more weight to the first syllable in rapid delivery. Maintain /æ/ in the first vowel across all variants.
The main difficulty lies in the /b/ followed by /s/ producing an abrupt /bs/ cluster and the final unstressed -sa sounding like /sə/ or /sɪ/; many speakers merge the /sɪk/ into /sɪk/ with reduced vowel sequences. Additionally, the two consecutive consonant clusters /bs/ and /ks/ demand precise timing, and the relatively light final schwa can fade in fast speech. Practice by isolating each segment: /æb/-/sɪk/-/sə/, ensuring crisp /b/ and /s/ and a distinct but short final /ə/.
Yes — the emphasis falls on the second syllable and the /ks/ cluster in /sɪk/ is clearly pronounced as /k s/ rather than a simplified /ks/ blend. Visualize the word as AB-SSIC-SA; keeping an emphasis on the middle syllable helps maintain the canonical rhythm: ab-SIC-suh. The presence of two sibilants in close proximity requires careful tongue position: keep the blade of the tongue against the alveolar ridge for /s/ and insert a brief /k/ before the /s/ to produce /ks/.

Abscissa comes from Latin abscissa ‘a cutting off, away from,’ from abscid- 'cut off,' from the verb abscindĕre ‘to cut off, detach,’ from ab- ‘away’ + scindĕre ‘to cut.’ The term entered mathematical usage in the early modern period as coordinate geometry formalized Cartesian graphs. The root scind- and its related forms appear in English in words like ‘scissor’ and ‘scind,’ but in mathematics, abscissa denotes the horizontal coordinate, the complement to the ordinate (the vertical coordinate). First recorded usage in mathematical literature dates to the 17th–18th centuries as analytic geometry matured under figures like Descartes’ analytic geometry and later textbooks standardized the term. The sense evolved from the general notion of “cutting off” a measurement to specify a fixed axis location, particularly the x-axis, rather than a line segment itself. Over time, ‘abscissa’ became a precise term in coordinate geometry with a fixed, conventional spelling and pronunciation, distinguishing it from more colloquial phrases like “x value.”
