6. Edge Case Review:

The sequence "-sup-" presents a potential ambiguity. It could be divided as "su-pres" or "sup-pres". However, the common pronunciation and the presence of the "s" sound before a consonant favor "sup-pres".

7. Grammatical Role:

"Immunosuppression" primarily functions as a noun. While theoretically, one could attempt to use it adjectivally (e.g., "immunosuppression therapy"), the stress pattern and syllabification remain consistent.

8. Definition & Semantics:

• Definition: The suppression of the immune system, typically to prevent rejection of transplanted organs or to treat autoimmune diseases.
• Grammatical Category: Noun
• Synonyms: Immunodepression, immune inhibition
• Antonyms: Immunostimulation, immune enhancement
• Examples:
  • "The patient underwent immunosuppression following the kidney transplant."
  • "Long-term immunosuppression can increase the risk of infection."

9. Phonological Comparison:

• Compression: com-pres-sion - Similar structure with a prefix and a suffix "-sion". Stress falls on the penultimate syllable.
• Suppression: su-pres-sion - Shares the "-sion" suffix and similar stress pattern.
• Repression: re-pres-sion - Again, shares the "-sion" suffix and similar stress pattern.

These words demonstrate a consistent pattern of syllabification and stress assignment for words ending in "-sion". The initial consonant clusters are also similar, influencing syllable onset complexity.

10. Division Rules:

• Onset Complexity: Syllables can tolerate complex onsets (e.g., "im-", "sup-").
• Vowel Rule: Each syllable generally contains a vowel sound.
• Consonant Cluster Rule: Consonant clusters are often split based on sonority, but in this case, "sup-" is maintained as a unit due to pronunciation.
• Stress Rule: Penultimate syllable stress in words ending in "-ion".

11. Special Considerations:

The initial "im-" is a common prefix, and its syllabification is straightforward. The "no" sequence is a relatively simple syllable. The "-pres-" sequence is the most complex, requiring consideration of pronunciation.

12. Alternative Pronunciations/Regional Variations:

While the provided IPA transcription represents the most common US English pronunciation, slight variations may occur. These variations are unlikely to significantly alter the syllable division.
