putting medicine into the body
The act of using a needle to put liquid medicine into someone’s body.
Модель уживання:
give [someone] an injection of [medicine]

Learners often confuse “injection” with “shot” or “jab.” All can mean the same thing in a medical context, but “shot” and “jab” are more informal. Some learners also say *“make an injection”* instead of the correct *“give an injection”* or *“have an injection.”*
Синоніми
shot (Very common in everyday speech, especially in American English; slightly more informal than “injection.”)
|
jab (Common especially in British and informal speech; often used for vaccines.)
Антоніми
oral medication (Medicine that is taken by mouth instead of being put into the body with a needle.)

adding money or resources
When extra money or energy is added to a company, project, or activity to help it grow or get better.
Модель уживання:
an injection of [money/resources/energy] into [something]
Поширена помилка:
Learners may take this meaning literally and imagine a physical needle. In this sense, “injection” is figurative and usually refers to money, resources, or energy in business or social contexts. It is also common to forget the preposition *“of”* and say *“an injection money”* instead of *“an injection of money.”*
Синоніми
infusion (Often used in business and finance for adding money or resources; slightly more formal than “injection.”)
|
boost (More general and informal; suggests an increase or lift rather than the specific idea of adding resources from outside.)
Антоніми
withdrawal (Removal of money or support, the opposite of adding it.)
|
cutback (A reduction in money or resources, contrasted with adding more through an injection.)

forcing liquid or gas into something
Putting a liquid or gas into something, often using pressure or a pump, for science or industry.
Модель уживання:
the injection of [liquid/gas] into [material/system]
Поширена помилка:
Learners sometimes think this technical use must be about medicine because of the medical sense. In scientific or industrial texts, “injection” often refers to fluids or gases being forced into systems, not into people.
Синоніми
pumping (Focuses on using a pump to move liquid or gas; less general and less technical than “injection.”)
Антоніми
extraction (Taking liquid or gas out of something, instead of forcing it in.)

engine fuel delivery system
The system in an engine that puts fuel into it at the right time and in the right amount.
Модель уживання:

Поширена помилка:
Learners may think “injection” here still involves a medical-style needle. In cars and engines, it refers to a mechanical system that sprays fuel, not a medical procedure.
Синоніми
fuel delivery system (Describes the function more generally and is less specific and technical than “fuel injection.”)
Антоніми
carburetion (Older method of mixing fuel with air using a carburetor instead of an injection system.)

malicious insertion of code
A way for attackers to put bad code or commands into a computer program or website so they can control it or get data.

[type] injection attack
Поширена помилка:

Синоніми
code insertion (More general and descriptive; lacks the strong technical security meaning that “injection” has.)
Антоніми

one-to-one mathematical function
In math, a function where every different input gives a different output, so no two inputs share the same output.
Модель уживання:
an injection from [set A] to [set B]
Поширена помилка:
Learners sometimes mix up “injection” with “surjection” or “bijection.” An injection is only about different inputs having different outputs, not about covering every element of the codomain.
Синоніми
one-to-one function (More explanatory and common in teaching; “injection” is the standard formal term in higher mathematics.)
Антоніми
many-to-one function (A function where different inputs can share the same output, the opposite property of an injection.)
