hedger

The word 'hedger' is a transparent English compound built from the Old English root hecg, which referred to a physical enclosure or boundary marker made of shrubs. The agent suffix -ere, also of Old English origin, was productively added to verbs and nouns to denote a person performing a related action or role. Thus, a 'hedger' literally meant "one who works with hedges." This concrete meaning evolved metaphorically in the world of finance during the 19th century. Just as a physical hedger creates a boundary to protect a field, a financial hedger takes actions to create a protective boundary against market risk, leading to the modern abstract sense of one who engages in hedging.
