Electric -Electricity Base form: Electric /ɪˈlektrɪk/ Change: When -ity is added, the vowel /ɪ/ in the second syllable changes to /ɛ/ → Electricity /ɪˌlɛkˈtrɪsɪti/. Reason/Rule: This is a vowel alternation (a morphophonemic process) caused by stress shift. The stress moves from the second to the third syllable, triggering a vowel reduction and change in the unstressed syllables.
2. Divide - Division Base form: Divide /dɪˈvaɪd/ Change: The vowel /aɪ/ changes to /ɪ/ → Division /dɪˈvɪʒən/. Reason/Rule: This is vowel alternation due to suffixation. When the suffix -sion is added, the stressed vowel changes because of morphophonemic vowel shortening and stress shift.
3. Sign - Signature Base form: Sign /saɪn/ Change: The diphthong /aɪ/ changes to the short vowel /ɪ/ → Signature /ˈsɪgnətʃər/. Reason/Rule: This is a vowel reduction process occurring when the base morpheme sign combines with the derivational suffix -ature, leading to stress shift and vowel weakening.
4. Heal -Health Base form: Heal /hiːl/ Change: The long vowel /iː/ becomes a short /ɛ/ → Health /hɛlθ/. Reason/Rule: This is an example of vowel shortening and quality change (ablaut). The addition of the morpheme -th causes the vowel to shorten and change to reflect the noun form derived from the verb.
5. Produce - Production Base form: Produce /prəˈdjuːs/ (verb) Change: The vowel /uː/ changes to /ʌ/ and stress moves → Production /prəˈdʌkʃən/. Reason/Rule: This is a vowel alternation and stress shift due to the addition of the suffix -tion. The stress moves to a different syllable, causing the vowel quality to change.
