Section 1: Orthoepy of Long ū & Homophone Triad in Literature

Morphology • Orthoepy

Orthoepy of Long ū & Yod-Dropping:
• Wheeler's specific warning: "Be careful in pronouncing ū, especially in duty, student, stupid, and tulip."
• In 19th and early 20th century elocution, orthoepists insisted on the palatal glide /j/ before /uː/ after coronal consonants (/ˈdjuːti/, /ˈstjuːdənt/, /ˈstjuːpɪd/, /ˈtjuːlɪp/), censuring glide-deletion ("dooty", "stoodent") as vulgar.
• Modern General American exhibits standard coronal yod-dropping (/ˈduːti/, /ˈstuːdənt/, /ˈstuːpɪd/, /ˈtuːlɪp/), while strictly retaining /j/ after labials, velars, and glottals: music (/ˈmjuːzɪk/), pupil (/ˈpjuːpəl/), human (/ˈhjuːmən/).

Homophone Triad “so, sow, sew” in Literature:
• so (/soʊ/): Adverb/conjunction (OE swā) modifying adjectives or clauses of extent/manner. Percy Bysshe Shelley writes: "How beautiful is night, / So calm, so still, so bright!"
• sow (/soʊ/): Agricultural verb (OE sāwan) meaning to scatter seeds on soil. Shelley writes: "Men must reap the things they sow" (echoing Galatians 6:7). Note noun heteronym sow (/saʊ/, female pig).
• sew (/soʊ/): Needlework verb (OE siwian). Shakespeare writes in Pericles: "I can sing, weave, sew, and dance."
