Section 1: Homophones, Heteronyms & Robert Burns' Lyric

Orthoepy • Heteronyms

Homophones vs. Heteronyms (Homographs):
• Homophones (Same Sound, Different Spelling): bough (/baʊ/) and bow (/baʊ/). Both share the diphthong /aʊ/, but bough preserves Germanic silent -gh (OE bōg, tree limb), whereas bow (bend) comes from OE būgan.
• Heteronyms / Homographs (Same Spelling, Different Sound): bow (/baʊ/ – bend/ship prow) vs. bow (/boʊ/ – archery weapon, ribbon knot, violin bow). Both are spelled <bow>, but represent distinct etymological roots (OE būgan vs. OE boga).

Robert Burns & Poetic Personification:
• Robert Burns (1759–1796): Scotland's national bard. This verse originates from his January 1793 poem Sonnet on Hearing a Thrush Sing on a Morning Walk. Burns personifies the resilient songbird chanting on a bare winter branch.
• Lilies Bow Their Heads: Wheeler pairs the bird on the bough with floral personification: flowers bowing their blossoms in the breeze or at dusk, anchoring the homophone in vivid nature imagery.
