The word “reserve” is deployed with remarkable versatility across literary texts, functioning both in concrete and abstract realms. In narratives with a military backdrop, reserve denotes forces deliberately held back for strategic deployment, as seen in arrangements by Barrie [1, 2] or tactical formations described in military memoirs [3, 4, 5]. At the same time, many authors employ the term to capture a character’s quiet self-restraint or deliberate withholding of thoughts and feelings, imbuing their dialogue or inner monologue with an air of controlled mystery [6, 7, 8, 9]. Additionally, reserve can suggest a postponement or careful saving of one’s judgments or resources, whether it is an idea kept for later creative flourish [10, 11] or the subtle discretion that marks refined social behavior [12, 13]. This multiplicity of meanings highlights the term’s adaptability, allowing writers to convey everything from military strategy to the inner dynamics of personal conduct.
