The sequence "-si-" before a vowel can sometimes be a point of variation, but in this case, it clearly forms a syllable on its own due to the vowel following it.

7. Grammatical Role:

• Examples:
  • "The patient reported experiencing extreme photosensitivity after the medication."
  • "Photosensitivity can be a symptom of certain autoimmune diseases."

9. Phonological Comparison:

• Sensitivity: sen-si-ti-vi-ty. Similar syllable structure, stress on the penultimate syllable. The addition of "photo-" adds a syllable at the beginning.
• Responsibility: re-spon-si-bi-li-ty. Similar suffix "-ity" and syllable structure. Stress pattern is also similar.
• Connectivity: con-nec-ti-vi-ty. Again, the "-ity" suffix and similar syllable structure. Stress pattern is also similar.

These comparisons demonstrate a consistent pattern of syllable division based on vowel sounds and the presence of suffixes like "-ity".

Detailed Syllable Analysis:

Division Rules Applied:

1. Vowel-Consonant-E Rule: Not applicable here.
2. Open Syllable Rule: Syllables ending in a vowel sound (pho, to, sen, si, ti, vi) are generally open syllables.
3. Closed Syllable Rule: Syllables ending in a consonant sound (ty) are closed syllables.
4. Consonant Cluster Rule: Consonant clusters are generally kept together within a syllable (sens).

Special Considerations:

The word's length and the presence of multiple vowels require careful consideration of syllable boundaries. The consistent application of the open/closed syllable rule and the preservation of consonant clusters ensure accurate division.

Alternative Pronunciations/Regional Variations:

While the provided IPA transcription represents the most common US English pronunciation, slight variations in vowel quality might occur depending on regional accents. These variations would not significantly alter the syllable division.
