fruiterer

From Late Middle English fruiterē̆r (“fruit grower; fruit dealer”), from fruitē̆r (“fruit dealer; household official having charge of fruit”) + -er (it is unclear why the second suffix was added). Fruitē̆r is derived from Anglo-Norman fruitier or French fruitier (“fruit-seller”), from fruit (“fruit”) (from Latin frū̆ctus (“produce, product, fruit; enjoyment, satisfaction”), ultimately from Proto-Indo-European *bʰruHg- (“to have enjoyment of; make use of”)) + -ier (suffix forming names of jobs).
