timeout

timeout — A timeout is an automatic system interrupt that occurs when a process or connection does not complete within a specified time limit.

In simple English

In software engineering, a timeout is triggered when an application or service waits longer than expected for a response or action. For example, if your code tries to connect to a database but receives no response within 30 seconds, a timeout error occurs and the request stops. Timeouts prevent applications from hanging indefinitely and wasting system resources. They are commonly used in network requests, database queries, API calls, and user interface interactions. Engineers set timeout values based on expected response times, and monitoring timeouts helps identify performance bottlenecks or service failures.

How to say it: Noun is one word: "timeout". Verb is two: "time out".

Say it like this

  • The request hit a timeout
  • We're getting timeout errors in production
  • Increase the timeout value to 60 seconds

Use it at work

Debugging

  • The request timed out after 30 seconds.
  • We're seeing timeouts on the payment API.

Design

  • Let's set a timeout of five seconds.
  • Add a timeout so the job doesn't hang forever.

Meetings

  • Let's take a five-minute timeout.
  • Quick timeout. I need to check something.

Don't say this

✕The system will timeout if you do not respond.
✓The system will return a timeout error if you don't respond.

Timeout is a noun referring to the error state, not a verb describing what the system does.

More about timeout

Real examples(3)

  • in a standup

    "We identified that the API timeout was set too low, causing requests to fail prematurely."

  • in a code review

    "Good catch—we should add a timeout configuration here to prevent the connection from hanging indefinitely."

  • in a team meeting

    "The database timeout has been increased from 5 to 15 seconds to accommodate slower queries during peak hours."

More mistakes(2)

Handle with care. Do not confuse timeout (a system interrupt) with time out (a rest break). Also, timeout is typically a noun in tech contexts; using it as a verb is less formal.

  • ✕We need a timeout to rest before the meeting.
    ✓We need a break before the meeting. (In tech, use 'timeout' only for technical processes.)

    In tech contexts, timeout refers to system interrupts, not rest periods.

  • ✕Set the timeout very high so it never happens.
    ✓Set an appropriate timeout value based on expected response time.

    Very high timeouts defeat the purpose of preventing resource waste; they should be realistic.

Other forms(3)

  • timeout noun

    "A timeout occurred during the database query."

  • timeout error noun

    "Users are seeing timeout errors when uploading large files."

  • timeout value noun

    "We need to increase the timeout value from 10 to 30 seconds."

Often used with(6)

  • timeout error · The most common phrase; refers to the specific error message returned when time limit is exceeded
  • timeout value · The configurable time limit set by engineers for a specific process or connection
  • connection timeout · Specifically refers to a timeout when establishing a connection to a remote service
  • request timeout · Refers to a timeout when waiting for a response to an HTTP or API request
  • set a timeout · To configure or establish a timeout value in code
  • increase the timeout · To extend the time limit to allow more time for a process to complete

Similar words(3)

  • connection timeout · More specific; refers only to timeouts during connection establishment
  • deadline exceeded · More formal term; less commonly used in everyday tech conversations
  • time limit exceeded · More descriptive but less concise than timeout

Opposites(3)

  • success
  • response
  • completion

Questions(5)

What does timeout mean in software engineering?
A timeout is an automatic interrupt that stops a process when it exceeds a specified time limit. It prevents applications from waiting indefinitely for a response that may never come, helping preserve system resources and improve user experience by returning an error instead of hanging.
How do you use timeout in a sentence at work?
You can say: 'We are experiencing timeout errors on the payment gateway' or 'Increase the timeout value to 60 seconds' or 'The request hit a timeout after waiting 30 seconds for the database response.'
Is timeout formal or informal?
Timeout is neutral and professional. It is standard terminology used in both formal documentation and casual team conversations. You can use it comfortably in code reviews, meetings, emails, and documentation.
Can timeout be used as a verb?
In formal tech English, timeout is primarily a noun. Instead of saying 'the system will timeout,' say 'the system will return a timeout error' or 'the system will timeout.' Using it as a verb is informal and best avoided in professional settings.
Why do we need timeouts?
Timeouts are essential safety mechanisms that prevent applications from hanging indefinitely when services are slow or unavailable. They allow systems to fail gracefully, trigger fallback behaviors, and help teams identify performance problems quickly.
