Four-Vowel Synthesis & Orthographic Logic (Educator Reference)

1. Diagnostic Review of Syllable Anatomy: Lesson 27 tests the child's ability to discriminate between the closed syllable pattern (consonant-vowel-consonant, producing short vowels marked with a breve ˘) and the open VCe split digraph pattern (where a final silent e conditions a long vowel marked with a macron ¯).

2. The Velar Nasal Assimilation in bank: Before the velar stop /k/, the nasal /n/ assimilates to the voiced velar nasal /ŋ/. While phonetically /bæŋk/, the vowel remains phonemically short ă.

3. The -ck Spelling Convention in sick: English phonotactics forbids writing single *c or *k directly after a short accented vowel at the end of a native monosyllable. The compound digraph -ck is strictly mandated (e.g., sick vs. lake / yoke).
