labour-saving

Synonym discussion
Sense: adjective/1
All four words describe something that reduces waste, but they highlight different aspects. Labour-saving is the most concrete: it refers specifically to a tool, machine, or method that cuts physical work or time — a dishwasher is labour-saving because it scrubs dishes by itself. Time-saving focuses narrowly on speed; a faster internet connection is time-saving but not necessarily labour-saving. Efficient is much broader and can apply to any system or person who uses resources well, whether or not a machine is involved. Automated stresses that a process runs without human effort — a factory robot is automated, but a well-organised filing system is not. Use labour-saving when the main benefit is doing less physical work; use time-saving when speed is the point.

Etymology
Formed by combining the noun 'labour' (physical or mental work) with the adjective 'saving' (preventing waste or reducing use). The compound pattern dates from the 19th century, when the Industrial Revolution created many new machines that were marketed as ways to reduce human effort in factories and homes.
