8. Grammatical Role:

"Ophthalmotonometry" functions solely as a noun. Syllabification and stress remain consistent regardless of its grammatical context (as it doesn't inflect).

9. Definition & Semantics:

• Definition: The measurement of the tension or pressure within the eye, typically used in the diagnosis of glaucoma.
• Grammatical Category: Noun
• Synonyms: Intraocular pressure measurement
• Antonyms: N/A (it's a measurement, not a state)
• Examples: "The ophthalmologist performed an ophthalmotonometry test to assess the patient's risk of glaucoma."

10. Alternative Pronunciations/Regional Variations:

Regional variations in RP might affect the vowel quality of certain syllables (e.g., /ɒ/ vs. /ɔ/). However, the core syllable division remains consistent.

11. Phonological Comparison:

• Biochemistry: bio-chem-is-try. Similar Greek-derived components and multi-syllabic structure. Stress on the second syllable.
• Psychometry: psy-cho-me-try. Similar suffix "-metry" and complex consonant clusters. Stress on the second syllable.

The key difference lies in the initial consonant clusters and the length of the word. "Ophthalmotonometry" has a more complex initial cluster and is longer, leading to a different stress pattern.
