Medieval Latin fungibilis = that can serve in place of, from fungi = to perform, enjoy; -bilis = capable of

📜 Etymology

From Medieval Latin fungibilis, derived from Latin fungi (to perform, discharge a function), from which also comes functio (performance). The term originates in Roman law (res fungibiles) to describe things that can be replaced by equal items of the same type. It entered English legal vocabulary in the 17th century and later spread to economics and financial market contexts.
