The variants of the lateral sound邊音 as in light and tell


(D) 的 wi”ves” 和 lea”ves”發音均相同可先刪除,剩下的關鍵在於“allomorphic”,因為涉及到morpheme (也就是最小有意義的單位),而 (B) 的”ed”有過去式的含義,固為答案,至於 (A) 和 (C) 都只是phoneme (最小的聲音單位)。

|
Phonological Conditioning |
The choice of an allomorph is determined by the sound structure and can be described by a phonological rule. |
1. English plural affixes: The choice of the plural morph depends on the final stem consonant, such as cats (following a voiceless consonant), dogs (following a voiced consonant), and horses (following an alveolar fricative). 2. English indefinite article: The variants include an (used before vowels), a stressed a (for emphasis), and an unstressed a (used elsewhere). 3. Vowel harmony: In Hungarian, the locative morpheme ben is used if the final stem vowel is a front vowel (e.g., leben), while ban is chosen if it is a back vowel (e.g., falban). Turkish also exhibits a similar situation. |
|
Morphological Conditioning |
The choice of a particular allomorph is determined by the morphological context. |
1. English word wife: Its genitive form(所有格 wife’s ) is phonologically conditioned, whereas its plural form (wives) represents a special morphological context that determines the choice of the allomorph. 2. Latin first-person singular: The choice of the form is dependent on the tense, using -o for the present tense base form (laudo), -m for the simple past (laudabam), and another variant for the present perfect. |
|
Lexical Conditioning |
The choice of an allomorph depends on a particular lexeme, semantic properties of the base, or cannot be derived by any rule at all and has to be learned. |
1. English past tense: The choice depends on the specific lexeme, such as buy becoming bought, while cry becomes cried (and not crot). 2. Persian plural marking: The choice depends on semantic properties (human vs. non-human). The word for man (merd, +human) takes the suffix -an (merdan), while the word for cat (gorbe, -human) takes the suffix -ha (gorbeha). 3. English past participle suffix -en: Speakers have to learn which specific verbs take this suffix, such as taken, seen, and given. |
