Section 1: The Orthographic Architecture of Wheeler's 8 Review Vowel Categories

Phonology • Diacritic Key

19th-Century Diacritic Notation vs. Modern IPA:
• Macron over double-o (ōō): Denotes long high back vowel /uː/ (woo, ooze, tooth, droop, choose).
• Italian a (ä): Denotes open back /ɑːr/ before /r/ (harsh, marsh, spark, starve).
• Broad a with lower dot (ạ): Denotes open-mid back /ɔː/ before -l (bald, scald, false, stall).
• Breve over ea (ĕa): Denotes short front vowel /ɛ/ (tread, dread, spread, thread).

Pedagogical Contrast Strategies:
• The /aʊ/ Diphthong Duo: Contrast Germanic ow (often preceding -l or terminal) with French/Anglo-Norman ou (preceding dental consonants -t, -th, -nd).
• The Nurse-Vowel Merger (/ɜːr/): Explain that historical Middle English distinguished ẽ (fern), ĩ (fir), and û (fur), which merged in modern English into the identical phoneme /ɜːr/.
