Lab Report 01
The 1-1-1 Doubling Formula
The Rule:
When a base word has 1 syllable, ends in 1 vowel, and has 1 consonant (the 1-1-1 rule), you must double that final consonant before adding a suffix starting with a vowel (-ed, -ing).
Experiment A: Apply the Formula
Base Word
1-1-1?
+ -ed
+ -ing
hop
hope
stop
dream
Experiment B: Vowel Team Integration
Vowel teams (ai, ay, ee) do NOT follow the doubling rule. Just add the suffix!
rain
play
keep
stay
