Synonym discussion
Sense: noun/1
Effort, energy, exertion, and hard work all relate to using your physical or mental resources, but they differ in focus. Effort adds the idea of willpower and determination — you push yourself to achieve something. Energy is the raw capacity you have; a task can require lots of energy without feeling like an effort if you enjoy it. Exertion is more formal and tends to describe physical strain ('The exertion of climbing left him breathless'). Hard work emphasises the difficulty or duration rather than the mental push ('Years of hard work built the business'). In practice: 'She put tremendous effort into learning Mandarin' highlights her determination; 'She had the energy to study all night' highlights her capacity; 'Studying was hard work' highlights the difficulty.

Etymology
Effort entered English in the 15th century from Old French 'esforz', meaning 'force, exertion'. The French word came from Latin 'ex-' (out) + 'fortis' (strong), literally meaning 'a putting forth of strength'. The original sense was purely physical — applying force to overcome resistance. By the 17th century, the meaning had expanded to include mental exertion and organised undertakings, giving us the four main senses in use today.
