5. Phonetic Transcription:

/pɐˈvʲerxnəstnə ˈaktʲɪvnɨj/

6. Edge Case Review:

Russian syllabification generally follows the sonority hierarchy, but vowel reduction in unstressed syllables is significant. The "о" in "поверхностно" is reduced to /ɐ/ in the first syllable. The palatalization of consonants before "е", "ё", "и", "ю", "я" is crucial.

7. Grammatical Role:

The word is primarily an adjective. Syllabification and stress remain consistent regardless of its grammatical function within a sentence.

8. Definition & Semantics:

• Definition: Relating to or characterized by surface activity; surfactant.
• Translation: Surface-active
• Grammatical Category: Adjective
• Synonyms: поверхностный (poverkhnostnyy - superficial), активный (aktivnyy - active)
• Antonyms: инертный (inertnyy - inert)
• Examples:
  • "поверхностно-активные вещества" (poverkhnostno-aktivnyye veshchestva) - "surface-active substances"
  • "поверхностно-активный агент" (poverkhnostno-aktivnyy agent) - "surfactant"

9. Phonological Comparison:

• активный (aktivnyy): а-ктив-ный /ɐˈktʲɪvnɨj/ - Similar syllable structure, stress on the second syllable.
• поверхность (poverkhnost'): по-верх-ность /pɐˈvʲerxnəsʲtʲ/ - Shares the "поверх-" prefix, similar syllabification rules apply.
• активность (aktivnost'): ак-тив-ность /ɐkˈtʲɪvnəsʲtʲ/ - Shares the "актив-" root, similar syllabification rules apply.

The differences in syllable division and stress are primarily due to the length of the word and the presence of additional suffixes. The core principles of Russian syllabification remain consistent.
