Morpho-Phonological & Historical Orthography Notes:
1. The Silent -b in dumb: dumb descends from Old English dumb (silent /b/ after /m/). The final /b/ was pronounced in Proto-Germanic but underwent coda cluster reduction in Middle English. The spelling retains the historic etymological -b.
2. The Split Digraph V-C-e: In use, muse, cube, tube, mule, pure, the final silent -e signals the vowel to represent its alphabetic “long” value (/juː/ or /uː/), rather than the lax short vowel /ʌ/.
3. FLOSS Rule in buzz: Single-syllable base words ending in /z/ immediately preceded by a short vowel double the final letter (-zz).
