8. Definition & Semantics:

• Definition: Diethylaminoethanol is a colorless, viscous liquid with an amine-like odor. It is used as an intermediate in the synthesis of pharmaceuticals, rubber chemicals, and other organic compounds.
• Grammatical Category: Noun
• Synonyms: N/A (specific chemical name)
• Antonyms: N/A

9. Phonological Comparison:

• Trichloromethane (chloroform): tri-chlor-o-meth-ane. Similar structure with multiple prefixes and suffixes. Stress falls on the penultimate syllable.
• Tetrahydrofuran: tet-ra-hy-dro-fu-ran. Similar in length and complexity, with multiple syllables. Stress falls on the second syllable.
• Isopropyl alcohol: i-so-pro-pyl al-co-hol. Similar in containing alkyl groups and alcohol components. Stress falls on the second syllable.

The differences in stress placement are due to the varying weight of the syllables and the presence of different vowel sounds. Diethylaminoethanol has a longer sequence of unstressed syllables before the primary stress, leading to a later stress placement.

10. Division Rules:

• Onset-Rime Principle: Syllables are formed around a vowel nucleus, with preceding consonants forming the onset and following consonants forming the rime.

• Vowel Combination Rule: Vowel digraphs and diphthongs are generally treated as a single vowel sound within a syllable.

11. Special Considerations:

The word's length and complexity make it prone to mis-syllabification. The presence of multiple vowels and consonant clusters requires careful application of the syllabification rules.

12. Alternative Pronunciations/Regional Variations:

Minor variations in vowel quality (e.g., the /æ/ in "amino" being slightly more open or closed) may occur depending on regional accents. However, these variations do not significantly affect the syllable division.
