Comprehensive resource for understanding and mastering English idioms
The idiom "burn the candle at both ends" means to work very hard and not take any time off, or to exhaust oneself by working too much. It is a figurative expression that compares the act of working long hours to the literal act of burning a candle from both ends until it runs out of wax.
The idiom "burn the candle at both ends" has been used in English since the 14th century, according to the Oxford English Dictionary. The earliest known use of the phrase was in the Middle English poem "A Dialogue Conteinyng the Nomber in Effect of All the Prouerbes in the Englishe Tongue," which appeared in 1387. In this poem, the idiom is used to describe someone who works so hard that they don't have time for anything else, including resting or spending time with their family. Over time, the meaning of the idiom has remained relatively stable, but its usage has become more common in contemporary language. It is now used to describe anyone who works long hours and doesn't take any time off, regardless of whether they are literally working 24/7 or not.
