IPA: /dɪˈbʌɡər/
KK: /dɪˈbʌɡər/
A tool or program used to find and fix errors in other computer programs by allowing the user to run the program step by step and check for problems.
The programmer used a debugger to identify and fix the errors in the code.
Debugger → It is formed from "de-" (meaning to remove or reverse) and "bug" (from the colloquial term for an error or flaw in a system) and "-er" (meaning a person who). The word "debugger" refers to a person or tool that removes errors from computer programs.
Think of someone who 'removes' ('de-') 'errors' ('bug') in a program — that's what a debugger does.
