/ˈsɪmbəl/
[noun] A mark, sign, object, or image that represents something else, such as an idea, feeling, or belief. For example, a heart shape is often used as a symbol of love.
A 'symbol' was originally a broken coin — two halves that proved two strangers once made a promise.
The story of the word 'symbol' begins in ancient Greece, with a beautifully concrete and human practice. The Greek word was *symbolon*, built from two parts: the prefix *sym-* (meaning 'together') and *ballein* (meaning 'to throw'). Literally, a *symbolon* was something 'thrown together.' But what did the Greeks actually throw together? Pieces of an object — most often a clay tablet or a coin — broken deliberately in two. Each party to an agreement kept one half. When they or their descendants met again, sometimes years or even generations later, they would fit the pieces together to verify their identities and confirm the original promise. The symbol was, at its heart, a device for recognition and trust.
This practice of token-based identification gave the word a broader life in Greek thought. Philosophers and rhetoricians extended *symbolon* to mean any sign, token, or mark that stood in place of something else — a word that pointed beyond itself. The concept was powerful precisely because it captured the idea of a *relationship* between two things: the visible piece and the invisible whole it recalled. Greek *symbolon* → Latin *symbolum* → this was the path the word took as it moved westward through the ancient world, carrying its philosophical weight with it.
Latin *symbolum* was used widely in early Christian writing, where it took on new religious significance. In this context, a *symbolum* was a creed or statement of faith — a compact summary that stood for a larger body of belief. The Apostles' Creed, for instance, was referred to as the *Symbolum Apostolorum*. The word here retained its Greek logic: a short formula that represented something much greater and deeper. This is how the word entered the language of the medieval Church, and through Church writing, into the educated vocabulary of medieval Europe.
From Latin *symbolum*, the word passed into Old French as *symbole*, and from there it was adopted into English during the 15th century, initially in religious and scholarly texts. Early English uses kept close to the Latin sense — a creed, a formal sign of belief. Over the following two centuries, the meaning expanded steadily. By the 17th century, writers were using 'symbol' to mean any visible sign that represented an abstract idea, whether in religion, mathematics, or literature. The broken-coin origin had been entirely forgotten; what remained was the pure, elegant idea of representation.
What is remarkable about the journey of this word is how its meaning moved from the intensely physical — a jagged piece of pottery clutched in a traveller's hand — to the almost entirely abstract. Today, a symbol can be a letter, a logo, a gesture, a colour, or even a sound. The original Greeks would perhaps be surprised to learn that their practical word for a clay token now sits at the centre of human communication, art, and psychology. Yet the core logic has never changed: a symbol is always something small that points to something larger, a fragment that implies a whole.
