## Meaning

To create an independent copy of a repository (codebase) so you can make changes without affecting the original project. As a verb, it means to create that copy; as a noun, it refers to the resulting copy itself.

In open-source development and collaborative projects, forking is a standard practice that allows developers to experiment, customize, or contribute to software without direct access to the main repository. When you fork a project on platforms like GitHub, you get a complete copy of all code, branches, and commit history. This is especially common in open-source communities where contributors fork a project, make improvements, and then submit a pull request to merge their changes back into the original. Forking differs from branching because a fork creates an entirely separate repository under your own account, while a branch remains part of the same repository. Teams also fork internally when working on experimental features or when creating specialized versions of a product for different clients.

## When you hear it

The developer forked the open-source project to add custom features for the client.

## Examples

- **in a standup:** "I forked the authentication service yesterday so I can test my changes without breaking the main branch."
- **in a code review:** "This fork diverged quite a bit from the upstream repository, so we should check if a merge is still feasible."
- **in a team meeting:** "We decided to fork the payment module because the client needs significant customizations that would not benefit the open-source community."

## What native speakers say

- "Can you fork this repo so we can work independently?"
- "I forked the main project to experiment with the new algorithm."
- "This is a fork of the original library with our custom modifications."

## Common mistakes

- ✗ "We forked the repository but stayed on the same codebase." → ✓ "We forked the repository and now have an independent copy." (Forking creates a separate, independent copy; if you are still sharing the same codebase, you have not truly forked it.)
- ✗ "I will fork a new branch for this feature." → ✓ "I will create a new branch for this feature." (Forking and branching are different operations; use 'branch' for parallel development within the same repo, and 'fork' for creating a separate copy.)
- ✗ "We should fork all changes back to master." → ✓ "We should merge all changes back to master." (You fork once to create a copy, but you merge branches and pull requests to integrate changes.)

## Be careful

Do not confuse with 'branch'—a fork is a complete copy of a repository, while a branch is a parallel line of development within the same repository.

## Word forms

| Part of speech | Word | Example |
| --- | --- | --- |
| verb | fork | I will fork the repository next week. |
| verb | forked | She forked the project last month. |
| verb | forking | Forking the codebase allows us to customize it for our needs. |
| noun | fork | This fork is maintained separately from the upstream project. |


## Collocations

- **fork a repository**: The most common usage; means to create a copy of a repo
- **fork the project**: Similar meaning; used when referring to the entire project rather than just the technical repository
- **upstream**: Used in context: 'We synced our fork with the upstream repository.'
- **pull request**: Often paired: 'After forking, she submitted a pull request to merge her changes.'
- **keep in sync**: Used together: 'We need to keep our fork in sync with the original.'

## Synonyms

- **copy**: More general; fork is specifically an independent copy of a repository with full history
- **clone**: Similar but different; cloning creates a local copy on your machine, while forking creates a server-side copy under your account
- **spin off**: Less technical; means to create a separate version, but lacks the specific version control meaning

## Opposites

- merge
- integrate

## FAQ

### What is the difference between forking and branching?

A fork creates a completely independent copy of a repository under your own account, with its own separate history and remote URL. A branch is a parallel line of development within the same repository and remains tied to the original project. Forks are typically used for independent customization or contributing to open-source projects, while branches are used for organizing work within a single project.

### When should I fork a repository instead of branching?

Fork when you want complete independence from the original project (such as creating your own version with custom features), when you do not have write access to the original repository, or when you plan to submit contributions back via pull requests. Branch when you are working on the same project and want to keep your changes organized but eventually merge everything back.

### Is fork formal or informal?

Fork is neutral and standard technical terminology used in both formal documentation and casual conversations among developers. It is appropriate in all professional contexts, from code reviews to management discussions.

### How do I sync my fork with the original repository?

You typically add the original repository as an 'upstream' remote, fetch updates from it, and then merge or rebase your fork against the upstream version. Most platforms like GitHub also provide a 'Sync fork' button to simplify this process.

### Can I delete a fork?

Yes, you can delete a fork at any time if you no longer need it. However, if you have pending pull requests, you should first check if they need to be completed or closed before deleting.
