Dwi Astuti Wahyu Nurhayati,The Morphological Process 47 THE MORPHOLOGICAL PROCESS OF ENGLISH CONVERSION Dwi Astuti Wahyu Nurhayati STAIN Tulungagung, East Java Abstract: This paper examines the morphological process of English conversion which produces the new morpheme or a process of word formation or a process of changing lexeme or changing the meaning from certain base. It includes concatenative morphology and non-concatenative (conversion included in non-catenatative). Conversion is derivational process whereby an item is adapted or converted to a new word class without the addition of an affix. The English conversion types covers direction conversion, partial conversion, deverbal, deadjectival, conversion to verb, conversion to adjective, minor categories of conversion, chnage of secondary word class: noun, verbs, adjectives, change with formal modifications. Keywords: Morphological process, English conversion A major way in which morphologists investigate words, their internal structure, and how they are formed is through the identification and study of morphemes, often defined as the smallest linguistic pieces with a grammatical function (Aronoff, 2005: 2). This definition is not meant to include all morphemes, but it is usual one and a good starting point. A moprheme may consist of a word, such as hand, or meaningful piece of a word, such as the –ed of looked, that can not be divided into smaller meaningful parts. Another way in which morphemes have been defined is as a pairing between sound and meaning. It may also run across the term morp. The term ‘morp’ is sometimes used to refer specifically to the phonological realization of morpheme. For example, the English past tense morpheme. For example, the English past tense morpheme that we spell –ed has various morphs. It is realised as (t) after the voiceless (p) of jump (cf. Jumped), as (d) after the voiced (l) of repel (cf. Repelled), and as (ₔd) after the voiceless (t) of root or the voiced (d) of wed (cf. Rooted and wedded). We can also call these morphs allomorphs or variants. Morphological process has several process one of them is conversion. Conversion is another morphological process which can change nouns to verbs (http://linguallyspeaking.wordpress.com/2009/11/04/noun-to-verb/). In conversion, the structure and sound of the words do not change, though the word class is different. Regard and regret are examples of words which are involved in this process – they do not require affixes to change the word class. Usually,
