Definition

Meaning

A person or device that puts a liquid, gas, or other substance into something with force.

In computing, a component or module that provides dependencies to an object or system (e.g., dependency injector).

Linguistics

Semantic Notes

Primarily refers to a mechanical device. The figurative/computing sense is a modern, technical extension of the core meaning.

Dialectal Variation

Examples

By Part of Speech

verb

British English

  • The system is designed to injector the fuel mixture efficiently.
  • They had to manually injector the serum.

American English

  • The mechanic will injector cleaner into the system.
  • The software needs to injector the dependencies.

Examples

By CEFR Level

B1
  • The car wouldn't start because of a dirty fuel injector.
  • The doctor used a new type of injector.
B2
  • A faulty injector can drastically reduce engine performance and fuel economy.
  • The new dependency injector simplified the application's code structure.
C1

Learning

Memory Aids

Mnemonic

Think of a doctor using a SYRINGE to INJECT medicine; an INJECTOR does a similar job, but for machines (fuel) or software (code).

Conceptual Metaphor

A TOOL FOR FORCIBLY INSERTING SOMETHING ESSENTIAL.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'инъектор' (direct cognate, correct). Avoid using it as a general word for 'syringe' (шприц).

Common Mistakes

  • Incorrect stress: pronouncing it as 'IN-jector' instead of 'in-JECT-or'.
  • Using it to mean a person who injects drugs (that is an 'injector' only in very specific technical reports, not common parlance).

FAQ

Frequently Asked Questions

It is a standard international technical term with no regional preference.

Rarely in everyday language. In technical/medical reporting, it might refer to a person administering injections, but 'injector' almost always refers to a device.

A syringe is a simple, manual device for medical use. An injector is typically a more complex, often automated, device used in machinery (like car engines) or specialised systems.

Because 'dependency injector' is a key design pattern that helps create testable, maintainable, and modular code by managing how objects get their dependencies.
