The word "retentive" is used across literature to underscore a quality of holding or preserving—whether referring to memory or to physical properties. Authors often describe characters as having a retentive memory, highlighting their ability to recall extensive details and render vivid recollections of events ([1], [2], [3]). At the same time, the term is applied to inanimate subjects, such as soil that retains water or substances ([4], [5], [6]), emphasizing a capacity to preserve or sustain. In some texts, it even makes appearances in more metaphorical or ironic contexts, suggesting an unyielding, sometimes oppressive, persistence ([7], [8]). This flexible use of "retentive" enriches both character portrayal and descriptive passages in literature.
