What does fanion mean?
A fanion is a small flag or pennant, historically used to mark positions and directions where something more permanent was impractical. In military use, regiments planted fanions to indicate the location of companies or headquarters on the field, and in surveying, fanions were set out at stations so that observers could sight along a line from a distance. The word comes from French and entered English around the seventeenth century, ultimately related to older terms for banners and hanging cloth such as the gonfalon. Today fanion is a rare word, encountered mainly in accounts of historic campaigns and in older surveying literature, which gives it a distinctly archival character. Though largely superseded by modern markers and electronic positioning, it remains a precise, evocative term for one of the simplest tools of coordination: a scrap of coloured cloth visible across a field, telling people exactly where to gather or where to look.

Etymology of fanion
Fanion was borrowed from French, where it arose as a diminutive form connected with 'fanon', a word for a piece of hanging cloth or banner. The same family of terms produced 'gonfalon', the name for a princely or civic banner in medieval Italy, and its officer, the gonfalonier. English adopted the word by the early modern period for the small flags used by troops and surveyors.
How fanion is actually used
A rare, chiefly technical term today, found mostly in historical military writing and old surveying manuals; it carries a formal, period flavour rather than everyday currency.
