5. Phonetic Transcription:

/ˌdaɪhɪdroʊˈsfɪŋɡoʊsiːn/

6. Syllable Breakdown & Rule Application:

Here's a detailed breakdown of each syllable, with IPA transcription, rule application, and potential exceptions:

• di-: /daɪ/ - Open syllable. Rule: Vowel followed by a consonant. Exception: None.
• hy-: /hɪ/ - Open syllable. Rule: Vowel preceded by a consonant. Exception: None.
• dro-: /droʊ/ - Open syllable. Rule: Diphthong followed by a consonant. Exception: None.
• sphing-: /sfɪŋ/ - Closed syllable. Rule: Consonant cluster followed by a vowel and consonant. Exception: The 'sph' cluster is a common initial consonant cluster in English, but requires careful articulation.

8. Grammatical Role:

"Dihydrosphingosine" primarily functions as a noun (a specific type of lipid). Syllabification and stress remain consistent regardless of grammatical context, as it's not inflected.

9. Definition & Semantics:

• Definition: Dihydrosphingosine is a sphingoid base, a component of certain lipids found in cell membranes. It's formed by the reduction of sphingosine.
• Grammatical Category: Noun
• Synonyms: Dihydro-sphingosine
• Antonyms: Sphingosine (the unsaturated form)
• Examples:
  • "Dihydrosphingosine levels were measured in the cell samples."
  • "The study investigated the role of dihydrosphingosine in cell signaling."

10. Alternative Pronunciations/Regional Variations:

Regional variations in vowel pronunciation (e.g., the /oʊ/ sound) are possible, but wouldn't significantly alter the syllable division. Some speakers might slightly reduce the vowel in the unstressed syllables.

11. Phonological Comparison:
