Debug
dee-BUG
/diːˈbʌɡ/
To identify and remove errors or defects (known as 'bugs') from computer hardware or software.
Debugging is a critical part of software development, often involving systematic testing, tracing code execution, and using specialized tools to locate the source of unexpected behavior.
The story behind the word. The term 'bug' to mean a defect or error dates back to the 19th century, famously used by Thomas Edison. However, its specific association with computers comes from a well-known incident in 1947. Grace Hopper, a pioneering computer scientist, found a moth trapped in a relay of the Mark II computer, causing it to malfunction. She taped the moth into her logbook, noting 'First actual case of bug being found.' From then on, 'debugging' became the standard term for fixing computer errors.
Word relationships
- troubleshoot: More general, can apply to any system (mechanical, electrical, software) to find the cause of a problem.
- rectify: To correct something, often implies a known error rather than the process of finding it.
- fix: A very general term for repairing anything.
Commonly confused with

Example sentences
- "The team worked late into the night to debug the critical issue before the product launch." Describing the process of fixing software.
- "A good integrated development environment (IDE) often includes powerful tools to help programmers debug their code." Referring to a tool.
- "Sometimes, the hardest part of programming isn't writing the code, but debugging it." Explaining a common challenge.
Memory hook
Imagine literally removing a 'BUG' (an insect) from your computer to make it work again. Remove the Bug
When not to use
While you can 'fix' any problem, 'debug' specifically refers to finding and resolving errors in technical systems, especially software.
Fun facts
- The original 'bug' (a moth) found by Grace Hopper is still preserved in the Smithsonian National Museum of American History.
- The process of debugging can often take more time than writing the initial code.
