Literary authors employ the term fervour to evoke an intense, almost tangible passion that drives characters’ actions and beliefs. It appears as the force behind ardent declarations of love and desire ([1], [2]), while also capturing the deep spiritual zeal and resolute commitment seen in prayers, meditations, and ideological pursuits ([3], [4]). In narratives ranging from the witty banter of social interactions to the sublime expressions of religious or artistic devotion, fervour becomes a bridge between inner emotions and outward actions. Whether it is used to illustrate a character’s impassioned outburst or to describe the steady, burning light of inner conviction ([5], [6]), the word enriches the texture of the prose by emphasizing a state of heightened feeling and intensity that can transform the mundane into the extraordinary.
