without a second thought
Meaning
To do something instantly or instinctively, without any hesitation, deliberation, or reconsideration.
Origin
The concept of a 'second thought' – a moment of reconsideration after an initial impulse – has been understood for centuries. Indeed, earlier English writings often show individuals having 'second thoughts' when faced with a decision. However, it was during the bustling 19th century that the phrase 'without a second thought' truly took root and flourished. This vivid construction quickly became a popular way to describe actions so immediate and instinctive they bypassed all deliberation. It captured the raw speed of a spontaneous reaction, making it the perfect verbal shorthand for everything from courageous rescues to reckless impulses, highlighting a deed performed with absolute, unhesitating conviction.
Examples
- When her friend called for help moving furniture, Sarah agreed to assist without a second thought.
- He jumped into the freezing lake to rescue the struggling dog without a second thought for his own safety.
