1 It means that they are the variation of the same morpheme. They have the same meaning, but different sounds. Green concludes that some cases of absent past tens markers in AAE are actually a product of morphological rather than morphological factors, because he believes that when past tense allomorphs [-t] and [-d] follow a stop that has the same characteristics voiced of the allomorph (e.g., walked), zero marking of the past tense form is possible. He also believes that this effect for context is considered a phonological constraint imposed by a consonant cluster reduction rule, rather than a zero-marking rule at the morphological level. Another reason is that when the allomorphs [-t] and [-d] follow vowels (e.g., cried) or are preceded by a continuous consonant (e.g., kissed), zero-marking is less likely to occur. So, if past allomorphs do not follow a stop sound but instead follow a vowel, there will not be a zero sign. This shows the phonological system of AAE which does not allow two stop consonants to be at the end of a word. This clearly helps us to determine the feature as a phonological feature. This distinction is important to Pruitt and Oetting, because they conducted studies on past tense marking by AAE-speaking elementary school children and believed that the cause of this feature is morphological rather than phonological rather than morphological. It is important for elementary school teachers since a considerable number of students will be AAE students and knowing what causes this characteristic is an important factor for teachers to teach effectively and help students accordingly. This descriptive and quantitative data could be of great use for the central part of the article, with all these relationships and components of semantics one can easily do the semantic analysis of a sentence. This is important because dissecting words at the sentence level will provide ground for further analysis by breaking down the codes and meanings of words, phrases, and sentences. It is very important to know semantics for good linguistic analysis because basic linguistic analysis of a sentence first starts by analyzing the largest unit which are words and knowing the components of semantics will really help to classify these words into groups and subgroups and labeling their references in this way semantics does the best job for linguistics maintaining the organization of the meaning of words. Knowing semantics is fundamental human knowledge and still contributes to linguistics and our everyday language. Without semantics, linguistic analysis will not be present.
