Origin

Mid 16th century (denoting force or vigour of expression): from French énergie, or via late Latin from Greek energeia, from en- 'in, within' + ergon 'work'.

work from Old English:
Work is connected with the Greek word ergon, which is the source of energy (late 16th century), ergonomic [1950s], and surgeon. Wrought, meaning ‘made in a particular way’ and found in wrought iron (early 18th century), is the old past form of work, which people used where we now use worked. Wright, a common surname that means ‘maker’ and is found in words such as shipwright (Old English) and wheelwright (Middle English), is also closely related to work. The first workaholic was mentioned in 1968. Since then we have had chocaholics and shopaholics, but the first word to be formed in this way from alcoholic was foodaholic, in 1965. The dictum ‘Work expands so as to fill the time available’ is known as Parkinson's law. It was first expressed by Professor C. Northcote Parkinson in 1955. Much older is the proverb All work and no play makes Jack a dull boy, which is first found in 1659. See also devil
