Following GB English syllabification rules, which prioritize vowel sounds and avoid splitting consonant clusters where possible, the word breaks down as follows (using only original letters):

3. Morphemic Analysis:

• Prefix: dextro- (Latin, meaning "right" or "right-handed"). Morphological function: Specifies the stereoisomer.

5. Phonetic Transcription:

/ˌdɛks.trəʊ.æm.fɪˈtæ.miːn/

6. Syllable Breakdown & Rule Application:

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

• dex /dɛks/ - Open syllable. Rule: Onset-Rime structure. 'd' is the onset, 'ex' is the rime. No exceptions.
• tro /trəʊ/ - Closed syllable. Rule: Consonant cluster 'tr' forms the onset, 'o' is the nucleus. Potential exception: The diphthong /əʊ/ could be analyzed as a complex nucleus.
• am /æm/ - Closed syllable. Rule: 'a' is the nucleus, 'm' is the coda. No exceptions.
• phe /fɪ/ - Closed syllable. Rule: 'f' is the onset, 'i' is the nucleus. No exceptions.
• ta /tæ/ - Open syllable. Rule: 't' is the onset, 'a' is the nucleus. No exceptions.
• mine /miːn/ - Closed syllable. Rule: 'm' is the onset, 'iː' is the nucleus, 'n' is the coda. Potential exception: The long vowel /iː/ could be considered a complex nucleus.

7. Edge Case Review:

The word's length and complex morphology present a challenge. The potential for schwa reduction in unstressed syllables (particularly in 'tro' and 'am') is a key consideration.

8. Grammatical Role:

"Dextroamphetamine" primarily functions as a noun (a specific chemical compound). It doesn't typically change form to function as other parts of speech, so syllabification and stress remain consistent.

9. Definition & Semantics:

• Definition: A stimulant drug used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy.
• Grammatical Category: Noun
• Synonyms: Adderall (brand name), amphetamine
• Antonyms: Sedatives, depressants
• Examples: "The doctor prescribed dextroamphetamine to help manage his ADHD symptoms."

10. Alternative Pronunciations/Regional Variations:

While the provided IPA transcription represents a standard GB pronunciation, slight variations may occur. Some speakers might reduce the vowel in 'mine' to a schwa /mɪn/. This wouldn't significantly alter the syllable division.

11. Phonological Comparison:

• amphetamine: am-phe-ta-mine. Similar structure, stress on the penultimate syllable.
• methamphetamine: me-tha-m-phe-ta-mine. Similar structure, stress on the antepenultimate syllable.
• dextrose: dex-trose. Similar prefix, stress on the first syllable.

The key difference lies in the length and complexity of the root. "Dextroamphetamine" has a longer root than "dextrose" and "amphetamine", leading to more syllables. The stress pattern is consistent with the general rule of stressing the penultimate syllable in multi-syllabic words.
