3. Morphemic Analysis:

• Prefix: methyl- (Greek methy- meaning 'malt', historically related to 'wine' and used to denote a one-carbon group) - functions as a chemical prefix indicating a single methyl group (-CH3).
• Root: cholanthr- (derived from chol- relating to bile, and anthr- relating to the anthracene hydrocarbon) - forms the core of the molecule's structure.
• Suffix: -ene (Greek origin) - indicates the presence of a double bond in the hydrocarbon structure.

4. Stress Identification:

The primary stress falls on the fourth syllable: me-thyl-cho-lan-threne.

5. Phonetic Transcription:

/ˌmɛθɪlˌkɒlænˈθriːn/

6. Syllable Breakdown & Rule Application:

7. Edge Case Review:

The combination of consonant clusters (e.g., th, chl) requires careful articulation. The vowel sounds are relatively standard in British English.

8. Grammatical Role:

"Methylcholanthrene" functions primarily as a noun, referring to a specific chemical compound. Syllabification and stress remain consistent regardless of grammatical context.

9. Definition & Semantics:

• Definition: Methylcholanthrene is a polycyclic aromatic hydrocarbon (PAH) used extensively in cancer research as a potent carcinogen.
• Grammatical Category: Noun
• Synonyms: 3-methylcholanthrene, MCA
• Antonyms: (None applicable - it's a specific chemical compound)
• Examples: "Exposure to methylcholanthrene can induce tumors in mice." "Researchers used methylcholanthrene to study the mechanisms of carcinogenesis."

10. Phonological Comparison:

Let's compare with three similar words:

• methanol: me-than-ol /ˌmɛθəˈnɒl/ - Similar syllable structure, stress on the second syllable.
• cholesterol: cho-les-ter-ol /kəˈlɛstərɒl/ - Similar root (chol-), but different suffix and stress pattern.
• anthracene: an-thra-cene /ænˈθriːsiːn/ - Shares the anthr- root, similar stress pattern, but simpler overall structure.

The differences in syllable division and stress are primarily due to the varying lengths and complexities of the suffixes and prefixes.

11. Division Rules:

• Onset-Rime: Syllables are generally divided based on the onset (initial consonant(s)) and rime (vowel and following consonants).
• Vowel-Centric: Each syllable typically contains one vowel sound.
• Consonant Clusters: Consonant clusters are often split based on sonority (loudness), with more sonorous sounds tending to belong to the following syllable.
• Stress Assignment: Stress is influenced by syllable weight (number of syllables) and morphological structure.

12. Special Considerations:

The word's length and complex structure make it prone to mispronunciation. The presence of multiple consonant clusters requires careful articulation.

13. Short Analysis:

"Methylcholanthrene" is a five-syllable noun with primary stress on the fourth syllable (/ˌmɛθɪlˌkɒlænˈθriːn/). It's composed of the prefix methyl-, root cholanthr-, and suffix -ene. Syllable division follows standard English (GB) rules based on vowel-centricity and onset-rime structure.
