7. Exceptions/Special Cases for the Word as a Whole:

• The word's length and complex morphology make it an unusual case for typical English syllabification.
• The presence of multiple roots (phenol, sulphone, phthalein) creates a compound structure that doesn't neatly fit standard affixation patterns.

• Antonyms: None applicable.
• Examples: "Phenolsulphonephthalein is commonly used in laboratory experiments to visualize cellular structures."

10. Alternative Pronunciations/Regional Variations:

Pronunciation variations are minimal, primarily concerning the vowel sounds. Some speakers might pronounce /fθæ/ as /fæ/. This would not affect the syllable division.

11. Phonological Comparison:

• Photography: pho-to-gra-phy. Similar initial 'pho-' syllable, following the V-C rule.
