What does pith mean?
Pith is a compact, versatile word with both concrete and figurative uses. Literally, it is the soft or spongy tissue inside a plant, such as the white layer beneath the peel of an orange or grapefruit. In culinary contexts, pith may be removed because it can be bitter. Figuratively, pith means the essential substance, central idea, or most important part of a subject: a writer may say that the pith of an argument is its clearest point. The related adjective pithy describes something brief, concentrated, and forceful, while pithless describes something lacking substance or significance. Although pith can also be a verb meaning to remove the inner tissue of a plant or to pierce it, the noun senses are more familiar in modern English. The word is useful because it points both literally and figuratively to what lies at the heart of something.
The soft or spongy inner tissue of a plant, especially the white material between the peel and flesh of citrus fruits; also, the essential substance or central point of something.
"The pith of the orange gave the marmalade a slightly bitter flavor."
The figurative sense is especially common in phrases such as “the pith of the matter.”
To remove the pith from a plant or fruit, or to pierce or penetrate with a sharp point.
"The chef carefully pithed the peppers before roasting them."
The culinary meaning is more common in British English and specialist food preparation; the piercing sense is relatively uncommon.
The plural is rare. Pith is usually used as a mass noun when referring to plant tissue, and as a countable noun only in more specialized contexts.
"The discarded citrus piths were placed in the compost."
From the pith of a citrus fruit to the pith of an argument, this word moves from the inside of plants to the heart of ideas.

Where does pith come from?
The word comes through Middle English from Old English pitha, ultimately from Latin pitha, a borrowing associated with Ancient Greek pitha or pithos, meaning a jar or vessel. The plant-related sense developed from the idea of the material found inside a plant, while figurative senses such as “the pith of the matter” developed by analogy with an inner or essential core. Related forms including pithy, pithless, and pithiness preserve the same central idea of substance, force, or what lies at the core.

How pith is actually used
In its sense of essential substance or central point, pith is often used figuratively, especially in the expression “the pith of the matter.” The botanical sense is primarily associated with the soft inner tissue of fruits and vegetables, while the verb meaning involving removal of that tissue is chiefly practical and culinary. The separate piercing sense is relatively uncommon.
