Group Base Words Derived Words / IPA Rule Mechanism Teaching & Phonetic Notes
Group 1: -ing
(Drop silent -e)
give, have, come, write, blame, strive giving /ˈɡɪvɪŋ/, having /ˈhævɪŋ/, coming /ˈkʌmɪŋ/, writing /ˈraɪtɪŋ/, blaming /ˈbleɪmɪŋ/, striving /ˈstraɪvɪŋ/ Drop final silent -e before vowel suffix -ing Prevents incorrect forms like *giveing or *writeing. Note write has long ī; give/have have short vowels.
Group 2: -ing
(Doubling)
get, let, whip, run, pat, put getting /ˈɡɛtɪŋ/, letting /ˈlɛtɪŋ/, whipping /ˈwɪpɪŋ/, running /ˈrʌnɪŋ/, patting /ˈpætɪŋ/, putting /ˈpʊtɪŋ/ 1-1-1 Rule: CVC doubles final stop/nasal Doubling preserves the short vowel sound /ɛ, ɪ, ʌ, æ, ʊ/. Single letter would signal a long vowel (*wiping).
Group 3: -er
(Doubling)
red, big, thin, dim, wet, glad, hot, mad redder /ˈrɛdər/, bigger /ˈbɪɡər/, thinner /ˈθɪnər/, dimmer /ˈdɪmər/, wetter /ˈwɛtər/, gladder /ˈɡlædər/, hotter /ˈhɒtər/, madder /ˈmædər/ 1-1-1 Rule before comparative vowel suffix -er Short vowel adjectives doubling: *glad* has CCVC base; still 1 vowel followed by 1 consonant.
Group 4: -y
(Doubling)
fun, sun, fog, star, mud funny /ˈfʌni/, sunny /ˈsʌni/, foggy /ˈfɒɡi/, starry /ˈstɑːri/, muddy /ˈmʌdi/ 1-1-1 Rule before vowel suffix -y (/i/) star has r-controlled vowel; doubled rr preserves /ɑːr/ in derived adjective.
