For a long period of time, malapropisms have been used in literature for a character to feign ignorance, such as in Sheridan's play, The Rivals and are based on a character. in the room named Mme Malaprop. In the play, Ms. Malaprop used words incorrectly. For example, Ms. Malaprop would replace the word “apprehend” with “apprehend”. However, this feigned ignorance is now known as a psycholinguistically qualified speech error and can occur when words are substituted by an individual, even if the individual knows what the target word should be. In this essay, the theory of how malapropisms are lexicalized will be discussed in terms of the structure of the mental lexicon used to produce and understand speech. This will be done by examining Fay and Cutler's article Malapropisms and the Structure of the Mental Lexicon and their hypothesis of left-to-right theory in accordance with malapropisms and lexicalism. James R. Hurford's article, Malapropisms, Left-to-Right Listing, and Lexicalism, will express an oppositional point of view. Lexicalization can be defined by Harley (Harley, 2008) as the translation of a word from its semantic representation, or meaning, of a word to its phonological form, also called sound. (Harley, 2008) Lexicalization contains a two-step process, with the first step being based on meaning and the second step being based on phonology. When an individual produces a word for the first time, it moves from a semantic level to an intermediate level of individual words, the process of word choice is known as lexical selection. (Harley, 2008) The individual then retrieves the phonological form of the word produced during a stage known as phonological encoding. (Harley, 2008 These definitions in the middle of the article......the entire list of words in terms of malapropisms are listed as whole words and are determined by the left-to-right pattern can be considered sufficient if these whole words are listed only by their stem, without the derivational suffix. This can be completely ruled out by examining Hurford's theory of the mental lexicon listing words with the derivational and inflectional suffixes already attached to the word stem, which. makes Fay and Cutler's argument that the target and the error are a coincidence and is completely void (Hurford, 1981, p. 423) Further research should be done to determine whether lexical lists correlate with malapropisms are made with the whole word or not, and just the stem or whether or not the whole word contains suffixes and whether these words are entirely based on coincidence by their phonological similarities..
