Generally speaking, adjectives have a significant and remarkable contribution to the clarity and specification of our speech. More specifically, postpositive, exclamative and supplementive functions enable the language user to express his or her attitude toward a specific situation or action. This paper addresses the restricted use of adjectives in Hemingways novels, namely, The Sun Also Rises, 1926 and The Old Man and the Sea, 1952. It attempts to answer questions such as, are these functions used in the novels under study? Are they frequent or infrequent? To achieve the aim of this paper, it is hypothesized that Hemingway uses all these functions; nevertheless, he is restricted in his use of these functions. This research adopts a mixed approach paradigm in analyzing the data collected. This approach fits the adopted model which is Biber, et al. (1999). The data is collected from the aforementioned novels. It is analyzed descriptively and statistically. The paper concluded that while Hemingway employs all three types of adjective functions, he is extremely restricted in his use of the functions under discussion.
