In literature, the word "tenuous" often conveys a sense of fragility or insubstantiality, whether describing physical elements, abstract concepts, or interpersonal bonds. Writers use it to evoke images of barely perceptible sounds—such as the faint vibrations of a clavichord [1]—or to suggest the delicate nature of relationships and ideas, as in social trust or political allegiances [2][3]. It also appears in more literal descriptions, painting ethereal pictures like a slim, barely visible vapor [4] or a fragile bridge spanning a deep gorge [5]. Furthermore, the term is employed to capture the ephemeral quality of thoughts or dreams, hinting at how fleeting and insubstantial these mental impressions can be [6][7]. Through these varied uses, "tenuous" enriches the narrative by emphasizing the delicate balance between presence and absence, solidity and dissolution.
