# Squash Merge Meaning: What Squashing Commits Really Does > To combine multiple Git commits into a single commit, or to quickly fix and eliminate bugs or issues before release. - **Term:** squash - **Part of speech:** verb - **Pronunciation:** /skwɒʃ/ - **English level (CEFR):** B2 - **Register:** Casual, Both - **Region:** US and UK - **Topic:** [Code and Git terms](https://app.speaktechenglish.com/learn/topics/software-development-terms.md) - **Lesson:** https://app.speaktechenglish.com/learn/squash - **Last updated:** 2026-10-27 ## Meaning To combine multiple Git commits into a single commit, or to quickly fix and eliminate bugs or issues before release. It means to compress or flatten something into a more manageable form. In software development, squash has two primary meanings. First, it refers to a Git operation where you merge multiple commits into one, creating a cleaner commit history. This is commonly done before merging a feature branch into main. Second, it means to fix or eliminate bugs and issues rapidly, often used urgently when problems are discovered close to deployment. For example, a developer might say we need to squash these bugs before launch, meaning we must fix them quickly and completely. The term carries a sense of urgency and decisiveness in both contexts. ## When you hear it The team needs to squash the authentication bugs before tomorrow's release. ## Examples - **in a standup:** "We discovered three critical bugs yesterday, but our team managed to squash them all by end of day." - **in a code review:** "Before we merge this PR, can you squash your commits so we have a clean history?" - **in a team meeting:** "The QA team found several edge cases. We should squash these issues before the production deployment tomorrow." ## What native speakers say - "We need to squash this before shipping." - "Let's squash those commits into one." - "Time to squash all the remaining issues." ## Common mistakes - ✗ "We squashed the bug into the system." → ✓ "We squashed the bug before deployment." (You squash bugs out of or before the system, not into it. The preposition changes the meaning.) - ✗ "I will squash these commits tomorrow." → ✓ "I need to squash these commits before merging." (Squashing commits is typically done as part of the merging process, not as a delayed task.) - ✗ "We squashed the entire feature." → ✓ "We squashed the bugs in the feature." (You squash specific issues or commits, not entire features. Be precise about what you are squashing.) ## Be careful Do not confuse with the vegetable. In tech, squash always refers to combining commits or fixing bugs, never to physical compression or the sport. ## Word forms | Part of speech | Word | Example | | --- | --- | --- | | verb (base form) | squash | We squash bugs every sprint. | | verb (past tense) | squashed | The team squashed five critical issues yesterday. | | verb (present continuous) | squashing | They are squashing commits right now before the merge. | | noun | squash | This squash of commits makes the history clearer. | ## Collocations - **squash bugs**: Most common usage; means to fix and eliminate bugs quickly - **squash commits**: Git-specific; combining multiple commits into one during a rebase or merge - **squash issues**: General usage; to resolve and eliminate problems before deployment - **need to squash**: Often expressed as urgent or necessary action - **squash before release**: Indicates timing; must be done prior to shipping code ## Synonyms - **fix**: More general; squash emphasizes speed and urgency - **eliminate**: More formal; squash suggests complete removal - **crush**: Informal alternative; less common in formal tech contexts - **combine**: For the Git commits meaning; more neutral than squash ## Opposites - split commits - preserve history - introduce bugs ## Practice This lesson has 4 practice exercises with instant feedback on the page: https://app.speaktechenglish.com/learn/squash ## FAQ ### What does squash mean in software engineering? Squash has two main meanings in tech. First, in Git workflows, it means to combine multiple commits into a single commit to create a cleaner project history. Second, it means to quickly find and fix bugs or issues, often used when problems are discovered close to deployment. Both meanings convey the idea of compressing or consolidating something into a simpler, more manageable form. ### How do you use squash in a sentence at work? You can say things like We need to squash these bugs before launch or Can you squash your commits when you rebase? The first example uses it as fixing issues; the second uses it in the Git context. Both are common in tech teams. ### Is squash formal or informal? Squash is casual to neutral in formality. It is very common in engineering teams and code reviews, but you would not use it in formal executive presentations. It is appropriate for standups, pull request comments, and team meetings among developers. ### Why do developers squash commits? Squashing commits creates a cleaner Git history by combining many small, incremental commits into one logical commit. This makes it easier to understand what changes were made and to review the code. It is especially useful before merging feature branches into the main branch. ### What is the difference between squash and fix? While squash and fix are related, squash emphasizes urgency and speed, often implying that multiple issues or commits need to be handled quickly or compressed together. Fix is more general and does not carry that same sense of consolidation or urgency. ## Related - [Rebase](https://app.speaktechenglish.com/learn/rebase.md) - Full glossary: https://app.speaktechenglish.com/learn.md - Live lessons with a coach: https://app.mocklyenglish.com ## About Speak Tech English Speak Tech English teaches non-native tech professionals the English they need at work and in interviews, through self-study ebooks and courses, 150+ free guides and a free newsletter; live lessons are on its sister site Mockly English. - Shop: https://speaktechenglish.com/courses/ - All products (markdown): https://speaktechenglish.com/products.md - Free guides (markdown): https://app.speaktechenglish.com/guides.md - Tech English glossary (markdown): https://app.speaktechenglish.com/learn.md - Newsletter (10% off): https://speaktechenglish.com/#subscribe - Live lessons and mock interviews: https://app.mocklyenglish.com ## Notes for agents - Speak Tech English sells self-study material.
