/flɪŋ/
[verb] To throw something quickly and with force, often without careful aim. It can also mean to rush into an activity with great energy, or, as a noun, to have a short and exciting romantic relationship.
A word born from Viking tongues, 'fling' once meant to kick wildly — like a panicking horse.
The word 'fling' arrives in English carried on the ships of Scandinavian settlers, tracing back to Old Norse 'flengja', meaning to whip, flog, or strike with force. The Old Norse term was itself connected to a broader family of words suggesting sudden, violent movement — the kind of motion that happens before the mind can catch up with the body. When Norse-speaking peoples settled across northern Britain during the Viking Age, they brought this word with them, and it took root in the dialects of northern England and Scotland particularly strongly.
In its earliest English appearances in the 13th century, 'fling' carried a raw, physical energy. It was used to describe the wild kicking of horses, the flailing of limbs, and frantic, uncontrolled movement. There was nothing graceful about it — to fling was to move with urgency and abandon, throwing caution aside along with whatever object happened to be in one's hand. This sense of losing control, of giving in to a sudden impulse, ran through the word like a thread.
As Middle English settled and developed, the meaning of 'fling' began to stretch. The core idea of throwing — launching something through the air with energy and little precision — became dominant, while the older sense of wild kicking faded. By the 14th and 15th centuries, writers were using 'fling' freely to describe hurling objects, and the word had shed most of its specifically animal or bodily associations. It became a more general verb of forceful projection.
The word's journey into metaphor was almost inevitable. If you can fling a stone, you can also fling yourself into an adventure, fling open a door, or fling accusations at someone across a courtroom. By the early modern period, 'fling' was doing heavy metaphorical work in English prose and poetry — suggesting passion, recklessness, and a kind of joyful disregard for consequences. Shakespeare and his contemporaries used it with relish, appreciating the way its short, sharp sound matched the actions it described.
The noun form of 'fling' — meaning a brief period of carefree pleasure or a short romantic affair — is a relatively recent development, becoming firmly established in the 19th century. This usage grew directly out of the metaphorical sense: a 'fling' was what you did before you settled down, a moment of throwing yourself freely into life before responsibility came knocking. The phrase 'have a fling' captured the spirit of temporary abandon perfectly. What is remarkable is how a Viking word for flogging a horse evolved, over seven centuries, into a term for a summer romance — yet the original energy, that sense of sudden, unguarded motion, never quite left it.
