8. Definition & Semantics:

• Definition: The emission of light as a result of a chemical reaction.
• Grammatical Category: Noun
• Synonyms: bioluminescence, phosphorescence (though not entirely synonymous)
• Antonyms: None directly applicable.
• Examples: "Fireflies produce light through chemiluminescence." "The experiment demonstrated a clear chemiluminescence effect."

9. Phonological Comparison:

• Fluorescence: /ˌflʊəˈrɛsəns/ - Syllables: flu-o-res-cence. Similar structure with a prefix + root + suffix. Stress on the third syllable.
• Bioluminescence: /ˌbaɪoʊluːmɪˈnɛsəns/ - Syllables: bi-o-lu-mi-nes-cence. Similar structure, with a different prefix. Stress on the third-to-last syllable.

Detailed Syllable Breakdown & Rules:

Division Rules Applied:

1. Vowel After Consonant: When a vowel follows a consonant, a syllable break typically occurs before the vowel.
2. Open Syllable: Syllables ending in a vowel sound are considered open syllables.
3. Closed Syllable: Syllables ending in a consonant sound are considered closed syllables.
4. Consonant Clusters: Consonant clusters are generally kept together within a syllable.

Special Considerations:

The "che-" prefix is relatively stable in its syllabification. The "-escence" suffix consistently forms a separate syllable. The vowel sequences are straightforward.

Alternative Pronunciations/Regional Variations:

Minor variations in vowel quality (e.g., /ə/ vs. /ɪ/ in unstressed syllables) might occur, but these do not significantly alter the syllable division.
