英语语素及语素变体的音位制约和形态制约研究

语素既是语言中音义结合的最小单位,又是语法分析的最小单位.它可分为自由语素和粘着语素.通常情况下,语素在任何环境中只有一种形式,但也有一些语素的形式是变化的.语素的变体会受到语音和形态的条件制约.英语语素是英语的核心内容之一,通过掌握语素知识,学习者可以从形态学的角度去了解和学习英语词语的内部结构和构词规律,从而有助于学习者能更准确地用词、更有效地记词.

Analysis on Morphemes and Allomorphs' Phonological and Morphological Conditionings in English Language

Morpheme is the smallest unit in terms of the relationship between expressions and content,a unit which cannot be divided without destroying the meaning,whether it is lexical or grammatical.Morpheme can be represented by two types: free morpheme and bound morpheme.In most cases,some morphemes have no more than one invariable form while quite a few have their varieties,which are referred to as allomorphs.Allomorphs are often conditioned phonologically and morphologically by the relevant elements.To learn about morphemes and allomorphs will help English learners to apply the language appropriately and to keep the words in mind easily.
