1. yes, I sure the theory underlying that morphemes have their own meaning which can compose a word or morpholgical construction because morphemes are the smallest units of form that have a grammatical function and morpheme itself is a meaningful morphological unit of a language that cannot be further divided and then, it is Some words consist of two or more morphemes: unhappy(not satisfied or pleased with (a situation), happiness(the state of being happy), preview(an opportunity to view something before it is acquired or becomes generally available),children(plural form of child). the construction is unhappy = un + happy, Happiness = happy + ness,Preview = pre + view, children = child + ren.
2. yes, i think, i sure the theory underlying that morphological construction may belong to simple or complex word depending on the types of bound morpheme which composes the construction because Bound morphemes may be derivational orinflectional. derivational morphemes can create new word from other words.for example unhappy. the construction is un + happy,and then Inflectional morphemes,it is not changing meanings or parts of speech, but instead simply make minor grammatical changes necessary for agreement with other words for example walks = walk + s (it is not changing meaning), and then bound morphemes are also referred to as affixes, among which there are prefixes, in fixes, and
suffixes for example prefixes unhappy = un +happy, suffixes quickly = quick + ly.
3. because phonological is the system of contrastive relationships among the speech sounds that constitute the fundamental components of a language and lexical is relating to the words or vocabulary of a language,allomorf is any of two or more actual representations of a morpheme, such as the plural endings, clitics is an unstressed word that normally occurs only in combination with another word therefore that in linguistics, morphology is the identification, analysis and description of the structure of morphemes and other units of meaning in a language.
4. because Compounding is word formation process by which new words are formed by combining two or more independent words for example bittersweet,rainbow,sleepwalk and the meaning of syntax is the arrangement of words and phrases to create well-formed sentences in a language for example, "The boy loves his dog" follows standard subject-verb-object word order, and switching the order of such a sentence would change the meaning or make the sentence meaningless and Syntactic languages, such as English, use word order to indicate word relationships. Inflected languages. the word of "loves" is inflexional morphemes which have the construction, love + s.
