6. Edge Case Review:

The length of the word and the presence of multiple vowels and consonant clusters require careful application of syllabification rules. The "am" sequence is a potential point of ambiguity, but is treated as a single syllable due to its function as a linking element.

7. Grammatical Role:

"Tetramethylammonium" primarily functions as a noun, specifically a chemical name. Its syllabification and stress pattern remain consistent regardless of its grammatical role within a larger chemical context.

8. Definition & Semantics:

• Definition: A quaternary ammonium cation with four methyl groups attached to the nitrogen atom.
• Grammatical Category: Noun
• Synonyms: None commonly used; it's a specific chemical term.
• Antonyms: Not applicable.
• Examples: "Tetramethylammonium hydroxide is a strong base used in organic synthesis."

9. Phonological Comparison:

• "dichloromethane": di-chlor-o-meth-ane. Similar structure with multiple prefixes and a root. Stress falls on the second-to-last syllable, differing from "tetramethylammonium".
• "trimethylamine": tri-meth-yl-a-mine. Shares the methyl- root. Stress falls on the second syllable.
• "dimethylformamide": di-meth-yl-for-ma-mide. Similar in length and complexity. Stress falls on the third syllable.

The differences in stress placement are due to the varying number of syllables and the weight of different morphemes. Longer words tend to have more distributed stress patterns.

Detailed Syllable Analysis:

Division Rules Applied:

1. Onset-Rime Division: Syllables are divided based on the onset (initial consonant(s)) and rime (vowel and following consonants).
2. Consonant Cluster Rule: Consonant clusters are generally maintained within the onset.
3. Vowel-Consonant Division: When a vowel is followed by a consonant within a syllable, the syllable is divided after the vowel.

Special Considerations:

• The word's length and complex morphology require careful consideration of stress placement and syllable boundaries.
• The "am" sequence is treated as a single syllable due to its function as a linking element, despite potentially being divisible.
• Regional variations in pronunciation might slightly affect syllable boundaries, but the overall structure remains consistent.
