In "configuration", which syllable carries the primary stress?
Words ending in -ation place the primary stress on the syllable immediately before the suffix. So configuration is "con-fi-gu-RA-tion" /kənˌfɪɡjəˈreɪʃən/ — stress on "RA." This rule is reliable: "documentation" (docu-men-TA-tion), "implementation" (imple-men-TA-tion), "authentication" (authen-ti-CA-tion), "optimization" (opti-mi-ZA-tion). The "-tion" itself is never stressed; the stress always lands one syllable before it. This single rule fixes a huge number of long technical words.

In "security" and "compatibility", which syllable is stressed (suffix -ity)?
Words ending in -ity place the primary stress on the syllable immediately before the suffix. So security is "se-CU-ri-ty" /sɪˈkjʊərɪti/ and compatibility is "com-pa-ti-BIL-i-ty" /kəmˌpætɪˈbɪlɪti/. Likewise "scalability" (scala-BIL-i-ty), "availability" (availa-BIL-i-ty), "complexity" (com-PLEX-i-ty), "capacity" (ca-PAC-i-ty). The stress consistently falls on the syllable just before "-ity." This rule makes long abstract IT nouns predictable.

In "specific" and "asynchronous"... for words ending in "-ic", where is the stress?
Words ending in -ic place the primary stress on the syllable immediately before the suffix. So specific is "spe-CI-fic" /spəˈsɪfɪk/. Likewise "dynamic" (dy-NAM-ic), "atomic" (a-TOM-ic), "logic" -> "logical" (LOG-i-cal), "periodic" (peri-OD-ic), "algorithmic" (algo-RITH-mic). The "-ic" suffix reliably pulls stress to the syllable just before it. (A handful of exceptions like "Arabic" / "politics" exist, but the rule holds for the vast majority of technical terms.)

How does the stress shift between "photograph", "photographer", and "photographic"?
This classic example shows how suffixes move stress. "PHO-to-graph" (stress first) becomes "pho-TOG-ra-pher" (stress shifts to the second syllable before "-er") and "pho-to-GRA-phic" (stress shifts before "-ic"). The same happens in tech: "AL-go-rithm" -> "algo-RITH-mic", "PA-ra-meter" -> "para-MET-ric". Adding a suffix often relocates the primary stress. Recognizing these patterns helps you say derived technical words correctly without memorizing each one.

In "parameter" and "variable", where does the stress fall?
Parameter is stressed on the second syllable: "pa-RA-me-ter" /pəˈræmɪtər/. Variable is stressed on the first: "VA-ri-a-ble" /ˈvɛəriəbəl/. These two extremely common terms are often mis-stressed by learners. Do not say "PA-rameter" (wrong) or "va-RI-able" (wrong). Note "parameter" (pa-RA-me-ter) contrasts with "perimeter" (pe-RI-me-ter) — same stress pattern, different words. Stress is lexical here, not rule-driven, so these are worth memorizing.
