  1. MORPHOPHONEMIC CHANGE
    1. Word: Produce → Production

    Base Form: Produce

    Change: The final sound /s/ in produce changes to /ʃ/ in production.

    Explanation: When the suffix -ion is added, the /s/ sound changes to /ʃ/ for smoother pronunciation. This is called palatalization, a common morphophonemic process in English.

    2. Word: Deep → Depth

    Base Form: Deep

    Change: The vowel /iː/ in deep changes to /ɛ/ in depth, and the final /p/ changes to /θ/.

    Explanation: The vowel is shortened, and the consonant changes to form a noun. This results from historical vowel shortening and consonant alternation when forming abstract nouns.

    3. Word: Strong → Strength

    Base Form: Strong

    Change: The vowel /ɒ/ changes to /e/, and -ng becomes -ŋθ.

    Explanation: When forming the noun strength, there is both vowel modification and consonant addition. This change is due to historical phonological shifts in noun formation.

    4. Word: Describe → Description

    Base Form: Describe

    Change: The final /b/ changes to /p/, and -ion causes a shift in stress and vowel quality.

    Explanation: The change from -b- to -p- is an example of voicing alternation, where a voiced sound becomes voiceless before certain suffixes.

    5. Word: Wide → Width

    Base Form: Wide

    Change: The vowel /aɪ/ changes to /ɪ/, and the final /d/ becomes /θ/.

    Explanation: This is both a vowel shortening and consonant alternation that occurs when turning an adjective into a noun, to maintain smooth pronunciation and follow English morphological rules.

  2. 1. Knife (base form: knife /naɪf/) → Knives (plural form: /naɪvz/)
    Change: /f/ → /vz/
    Reason: Voicing assimilation; the voiceless /f/ becomes voiced /v/ before the plural suffix /z/.

    2. Sign (base form: sign /saɪn/) → Signal (derived form: /sɪɡnəl/)
    Change: /n/ → /ɡn/
    Reason: The /n/ sound shifts to /ɡn/ when followed by the suffix /-al/.

    3. Electric (base form: electric /ɪlɛktrɪk/) → Electricity (derived form: /ɛlɛktrɪsɪti/)
    Change: /k/ → /s/
    Reason: The /k/ sound shifts to /s/ before the suffix /-ity/, which starts with a high front vowel sound.

    4. Nation (base form: nation /neɪʃən/) → National (derived form: /næʃənl/)
    Change: /ˈneɪʃən/ → /næʃənl/
    Reason: Vowel shift; the diphthong /eɪ/ in "nation" changes to the short vowel /æ/ in "national" due to stress shift.

    5. Decide (base form: decide /dɪsaɪd/) → Decision (derived form: /dɪsɪʒən/)
    Change: /d/ → /ʒ/
    Reason: The /d/ sound shifts to /ʒ/ before the suffix /-ion/, which triggers a change in the preceding consonant sound.

    These changes illustrate how English words adapt phonologically when modified through inflection or derivation.

  3. 1.Knife (base form: knife /naɪf/) → Knives (plural form: /naɪvz/)
    Change: /f/ → /vz/
    Reason: Voicing assimilation; the voiceless /f/ becomes voiced /v/ before the plural suffix /z/.

    2. Sign (base form: sign /saɪn/) → Signal (derived form: /sɪɡnəl/)
    Change: /n/ → /ɡn/
    Reason: The /n/ sound shifts to /ɡn/ when followed by the suffix /-al/.

    3. Electric (base form: electric /ɪlɛktrɪk/) → Electricity (derived form: /ɛlɛktrɪsɪti/)
    Change: /k/ → /s/
    Reason: The /k/ sound shifts to /s/ before the suffix /-ity/, which starts with a high front vowel sound.

    4. Nation (base form: nation /neɪʃən/) → National (derived form: /næʃənl/)
    Change: /ˈneɪʃən/ → /næʃənl/
    Reason: Vowel shift; the diphthong /eɪ/ in "nation" changes to the short vowel /æ/ in "national" due to stress shift.

    5. Decide (base form: decide /dɪsaɪd/) → Decision (derived form: /dɪsɪʒən/)
    Change: /d/ → /ʒ/
    Reason: The /d/ sound shifts to /ʒ/ before the suffix /-ion/, which triggers a change in the preceding consonant sound.

    These changes shows how English words adapt phonologically when modified through inflection or derivation

  4. 1. Basic form: Electric
    Changed form: Electricity
    Change: /k/ → /s/
    Rule: Palatalization (Velar Softening) - The /k/ sound changes to /s/ before the suffix -ity, due to the influence of the following high front vowel.

    2. Basic form: Photograph
    Changed form: Photography
    Change: /f/ → /v/ (in some pronunciations)
    Rule: Spirantization - The /f/ sound may change to /v/ due to the influence of the following vowel and the rhythmic pattern of the word.

    3. Basic form: Sign
    Changed form: Signal
    Change: /ai/ → /i/
    Rule: Alternation of diphthong and monophthong - The diphthong /ai/ in "sign" changes to the monophthong /i/ in "signal", reflecting a historical change in pronunciation.

    4. Basic form: Receive
    Changed form: Reception
    Change: /iː/ → /ɛ/
    Rule: Vowel shift - The long vowel /iː/ in "receive" changes to /ɛ/ in "reception", illustrating a morphophonemic alternation.

    5. Basic form: Divine
    Changed form: Divinity
    Change: /ai/ → /i/
    Rule: Trisyllabic laxing - The diphthong /ai/ in "divine" changes to the short vowel /i/ in "divinity", due to the addition of the suffix -ity, which causes the vowel to become shorter.

  5. 1. Electric → Electricity
    - Base form: Electric
    - Change: "c" becomes "ci" (pronounced /s/)
    - Explanation: When the suffix -ity is added, the final consonant sound softens to fit English phonological patterns.

    ---

    2. Divide → Division
    - Base form: Divide
    - Change: "d" becomes "s" in pronunciation (/ʒ/)
    - Explanation: The suffix -sion causes a morphophonemic shift for smoother pronunciation.

    ---

    3. Produce → Production
    - Base form: Produce
    - Change: The stress shifts from the second syllable to the first
    - Explanation: Adding -tion changes the word from a verb to a noun, which alters stress placement.

    ---

    4. Please → Pleasant
    - Base form: Please
    - Change: The vowel sound changes from /iː/ to /ɛ/
    - Explanation: The suffix -ant triggers a vowel shift for morphological consistency.

    ---

    5. Sign → Signature
    - Base form: Sign
    - Change: The silent "g" in “sign” becomes pronounced in “signature”
    - Explanation: Morphological extension of the root reveals the historical phoneme that is usually silent.

    1. leaf → leaves
    - Base form: leaf
    - Change: /f/ → /v/ (voicing) + plural suffix ‑s realized as /z/.
    - Reason: This is a regular voicing alternation in English. Historically, the plural suffix ‑(e)s was voiced /‑əz/ after sibilants and voiced after vowels and voiced consonants. Although the vowel disappeared, the voicing rule persisted for certain nouns ending in a voiceless fricative, so the /f/ becomes its voiced counterpart /v/ to match the following voiced /z/.

    2. knife → knives
    - Base form: knife
    - Change: /f/ → /v/ (voicing) + plural ‑s realized as /z/.
    - Reason: Same voicing rule as above. The base ends in a voiceless fricative /f/. In the plural, the fricative becomes voiced /v/ to accommodate the voiced plural morpheme /‑z/.

    3. house (noun) → house /haʊs/ → houses /ˈhaʊzɪz/ (verb: house /haʊz/)
    - Base form: house /haʊs/ (noun)
    - Change: /s/ → /z/ (voicing) when the verb suffix ‑es is added.
    - Reason: Intervocalic voicing (between two vowel sounds) historically caused the voiceless /s/ to become voiced /z/. The same pattern appears in noun‑verb pairs like _use_ /juːs/ → _use_ /juːz/.

    4. wife → wives
    - Base form:wife
    - Change:/f/ → /v/ (voicing) + plural ‑s realized as /z/.
    - Reason: Another instance of the regular voicing alternation rule for nouns ending in a voiceless fricative /f/. The plural morpheme ‑(e)s surfaces as voiced /‑z/, triggering the voicing of /f/ to /v/.

    5. bath /bæθ/ → bathe /beɪð/ (verb)
    - Base form: bath /bæθ/ (noun)
    - Change: /θ/ → /ð/ (voicing) and vowel shift /æ/ → /eɪ/.
    - Reason: This illustrates two morphophonemic processes:
    a. Voicing of the final fricative /θ/ to /ð/ in the derived verb (a common pattern for forming verbs from nouns, e.g., _breath_ → _breathe_).
    b. Vowel shift (Great Vowel Shift remnants) where the short /æ/ in the noun shifts to a long /eɪ/ in the verb.
