The word “pith” is employed in literature in both literal and metaphorical ways. In physical descriptions, it often refers to the core or central tissue of plants and trees, as when it denotes the spongy substance inside a coconut or palm ([1], [2], [3]). Conversely, it is also used figuratively to express the essential or most substantial part of an idea, argument, or character, as seen when writers describe the “pith” of a story or the inner core of a person's resolve ([4], [5], [6]). In some passages, “pith” even extends to portray strength or spirit, whether it’s the endurance conveyed by “pith and marrow” or the vital energy in a character’s nature ([7], [8]). This dual usage enriches the word’s texture, allowing it to function as a concrete image in natural description and as a subtle metaphor for essence or vigor.
