The sentence “Mala is very fond with reading mystery books” contains an error in the use of the preposition following the adjective “fond.” The correct sentence is “Mala is very fond of reading mystery books.” This example illustrates how English sentence structure depends not only on the arrangement of words but also on the appropriate grammatical relationship between words. The sentence has the basic structure of a declarative sentence. “Mala” functions as the subject, “is” is the linking verb, “very” is an adverb modifying the adjective “fond,” and “fond of reading mystery books” forms the subject complement. The sentence can be structurally represented as: Subject + Linking Verb + Adverb + Adjective Phrase Mala + is + very + fond of reading mystery books. The subject “Mala” is a proper noun and performs the grammatical function of the subject. The verb “is” is a form of the verb “be.” Here, it does not express an action but links the subject to its complement. The word “very” is an intensifying adverb because it increases the degree of the adjective “fond.” The adjective “fond” expresses a feeling of liking
