Why Are There Two Spellings?
The difference between granddad spelling vs grandad spelling comes from natural language evolution, not grammar rules.
1. Spoken English influence
In spoken language:

granddad → grandad follows a natural pattern of simplification

Modern communication accelerated simplified spelling:
- shorter words are faster to type
- informal writing spreads quickly
- social media normalizes variation
This helped “grandad” become more widely used.
