## Meaning

A merge conflict occurs when two developers change the same lines of code in different branches, and the version control system cannot automatically decide which changes to keep. It requires manual intervention to resolve.

In modern software development, teams use version control systems like Git to manage code changes. When multiple developers work on the same file simultaneously in different branches, their changes may overlap. If Developer A modifies lines 10-15 in one branch and Developer B modifies the same lines in another branch, a merge conflict happens when Git tries to combine these branches. The system marks the conflicting lines and requires a developer to manually decide which code to keep, delete, or combine. Merge conflicts are a normal part of collaborative development and become more frequent in larger teams or on complex projects. Understanding how to resolve them efficiently is a critical skill for any software engineer working in a team environment.

## When you hear it

Sarah encountered a merge conflict when pulling the latest changes into her feature branch.

## Examples

- **in a standup:** "I spent an hour this morning resolving merge conflicts in the authentication module."
- **in a code review:** "Before we can merge this PR, we need to address the merge conflict in the database schema file."
- **in a team meeting:** "We're seeing more merge conflicts lately because multiple teams are working on the payment system simultaneously."

## What native speakers say

- "We hit a merge conflict on the main branch"
- "I need to resolve these merge conflicts before pushing"
- "There is a merge conflict between the two pull requests"

## Common mistakes

- ✗ "I will merge conflict this code tomorrow." → ✓ "I will resolve the merge conflict tomorrow." (Merge conflict is a noun describing the problem, not a verb describing the action. You resolve, fix, or handle conflicts, not merge conflict them.)
- ✗ "The merge conflict happened because the system is broken." → ✓ "The merge conflict happened because both developers modified the same lines." (Merge conflicts are normal and expected in team development, not signs of system problems. They occur due to overlapping code changes.)
- ✗ "We should avoid all merge conflicts at work." → ✓ "We should learn to handle merge conflicts efficiently." (Merge conflicts are unavoidable in collaborative development. The goal is not to prevent them but to resolve them quickly and correctly.)

## Be careful

Do not use merge conflict as a verb (saying you will merge conflict something). Use resolve, fix, or handle instead. Merge conflict is always a problem that occurs, not an action you perform.

## Word forms

## FAQ

### What does merge conflict mean in software engineering?

A merge conflict occurs when two or more developers modify the same lines of code in different branches. When Git tries to merge these branches together, it cannot automatically decide which version to keep, so it marks the conflicting code and requires a human to manually resolve it. This is a normal and expected part of collaborative software development.

### How do you use merge conflict in a sentence at work?

You typically use merge conflict when describing a problem you encountered or are currently handling. Example sentences: I found a merge conflict in the database migration file. We need to resolve these merge conflicts before we can ship the feature. The team spent time discussing how to handle merge conflicts more efficiently.

### Is merge conflict formal or informal?

Merge conflict is neutral in formality. It is appropriate in all professional settings including standup meetings, code reviews, technical documentation, and formal presentations. It is the standard technical term used by developers worldwide.

### What causes merge conflicts?

Merge conflicts are caused when multiple developers modify the same lines of code in overlapping sections of files. They occur most often when features are developed in parallel, when multiple people edit the same configuration file, or when cherry-picking commits. They are not caused by system failures but are a natural consequence of collaborative development.

### How do you resolve a merge conflict?

To resolve a merge conflict, you edit the conflicting file and choose which code to keep. Git marks conflicts with special markers (<<<<<<, ======, >>>>>>). You manually edit the file to remove the markers and decide which changes to include, then stage and commit the resolved file. Many teams use visual merge tools to make this easier.
