What is Debugging Glossary?
The purpose of this Debugging Glossary is to equip you with a foundational list of terms you'll frequently encounter when identifying and fixing errors in code, often called common coding mistakes. Understanding these terms is the first step to becoming proficient in troubleshooting code.
Below is a comprehensive table from our Debugging Glossary covering essential terms:
| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| Bug | Noun | An error, flaw, or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. | The program crashed due to a bug in the memory allocation module. |
| Debug | Verb | The process of identifying and removing errors from computer hardware or software. Find a detailed definition of 'debug' at Oxford Learner's Dictionaries. | I need to debug this script before we deploy it to production. We spent all morning trying to debug the new feature. |
| Debugger | Noun | A software tool used by programmers to test and debug programs. | The debugger allowed me to step through the code line by line. |
| Breakpoint | Noun | An intentional stopping or pausing place in a program, put in place for debugging purposes. | I set a breakpoint just before the function call to inspect the variable values. |
| Log | Noun/Verb | (Noun) A record of events or messages produced by a program. (Verb) To record events or messages. | Check the server log to see if any errors were recorded during the transaction. |
| Stack Trace | Noun | A report of the active stack frames at a certain point in time during the execution of a program. | The stack trace helped us identify the sequence of function calls leading to the error. |
| Error | Noun | A mistake or an incorrect action that produces an unintended result. Often synonymous with bug. | A syntax error prevented the code from compiling. |
| Exception | Noun | An anomalous or exceptional condition requiring special processing, often disrupting the normal flow of program execution. | The program threw an exception when it tried to divide by zero. |
| Crash | Verb/Noun | (Verb) For a program or system to suddenly stop working. (Noun) An instance of a program or system suddenly stopping. | The application would crash every time a user uploaded a large file. |
| Patch | Noun/Verb | (Noun) A piece of software designed to update a computer program or its supporting data, to fix or improve it. (Verb) To apply such a piece of software. | The developers released a patch to fix the security vulnerability. |
| Root Cause | Noun | The fundamental reason for the occurrence of a problem or an incident. | Identifying the root cause of the bug took several hours of debugging. |
| Reproduce (a bug) | Verb | To be able to make a bug or error happen again reliably, which is essential for diagnosing and fixing it. | We can't fix the bug if we can't reproduce it consistently. |
| Memory Leak | Noun | A failure in a program to release discarded memory, leading to impaired performance or failure. | The application became slower over time due to a memory leak. |
| Syntax Error | Noun | An error in the syntax of a sequence of characters or tokens that is intended to be written in a particular programming language. | A missing semicolon caused a syntax error that the compiler caught. |
| Runtime Error | Noun | An error that occurs during the execution of a program, as opposed to a compile-time error. | Accessing an uninitialized variable can lead to a runtime error. |
Learning this vocabulary is not just about knowing words; it's about understanding the concepts behind them. A strong grasp of these terms from our Debugging Glossary will enable you to communicate more precisely with colleagues, understand technical documentation better, and ultimately become more effective at finding and fixing bugs. These are core skills for any aspiring developer.

Common Phrases Used
Beyond individual words from the Debugging Glossary, certain phrases are frequently used when discussing debugging techniques. Learning these expressions will help you communicate more effectively and understand the nuances of technical discussions. These vocabulary tips are essential for clear communication among developers.
Here are some common phrases you'll hear, expanding on the core concepts from the Debugging Glossary:
| Phrase | Usage Explanation | Example Sentence(s) |
|---|---|---|
| "Step through the code" | To execute code line by line using a debugger to observe its behavior and variable states. | Let's step through the code in the debugger to see where the value changes unexpectedly. |
| "Isolate the problem" | To narrow down the part of the code or system where an error is occurring. | We need to isolate the problem to a specific module before we can fix it. |
| "Reproduce the bug" / "Can't reproduce" | "Reproduce the bug" means to make the error happen again. "Can't reproduce" means the error is not consistently appearing, making it harder to debug. | The first step in fixing a bug is to reliably reproduce the bug. If you can't reproduce it, it's very difficult to diagnose. |
| "Roll back the changes" | To revert to a previous version of the code or system, often done when a new deployment introduces critical bugs. | The latest update caused major issues, so we had to roll back the changes to the stable version. |
| "File a bug report" | To formally document a bug, usually in a tracking system, providing details about how to reproduce it, its severity, and observed behavior. | If you find an issue, please file a bug report with detailed steps. |
| "Hotfix" | A quick fix for a critical bug, often applied directly to a live production system. | We deployed a hotfix last night to address the critical security vulnerability. |
| "It works on my machine" | A common, often frustrating, response from a developer when they cannot reproduce a bug that someone else is experiencing. It highlights differences in environments. | The tester reported a bug, but the developer said, "It works on my machine," so now they need to check environment configurations. |
Using these common phrases correctly can significantly improve your interactions within a development team. They often convey complex actions or situations succinctly. Familiarity with this kind of technical English helps bridge communication gaps and makes collaborative debugging processes smoother.
