The word plainly functions in literature as a marker of clarity and unambiguous communication. Authors use it both to denote the obvious character of descriptions and to stress the directness of a statement. In some passages, it enhances the depiction of physical attributes or straightforward actions, as when clothing is described in a matter-of-fact way [1] or a person's presence is noted without pretense [2]. In other contexts, it reinforces the unmistakable nature of a claim or point, making abstract or complex ideas more accessible, for instance in discussions of historical or philosophical assertions [3] and even in the articulation of emotional states [4]. This versatile use effectively cuts through elaboration, signaling that what follows is to be understood in its simplest and most direct form [5].
