1
formal introduction to a role or group
The official time when someone is welcomed into a new job, position, or group and is given first information or training.
Tipar de utilizare:
the induction of [someone] into [a job/organization]
Greșeală frecventă:
Learners sometimes confuse "induction" with "introduction" and use *induction* in everyday informal contexts where native speakers would say "Let me introduce you." "Induction" is usually used for formal or organized processes in workplaces, schools, or official groups, not for casual social meetings.
Sinonime
orientation (Common in workplaces and schools; focuses slightly more on practical information and training than on formality or ceremony.)
|
onboarding (Business jargon; emphasizes the whole process of helping new employees adjust to a job or company.)
Antonime
dismissal (Refers to formally removing someone from a job, the reverse of formally bringing them into it.)

reasoning from examples to general rule
A way of thinking where you look at many examples and then say what is usually true for all similar cases.
Tipar de utilizare:
induction from [examples/observations] to [a general rule]
Greșeală frecventă:
Learners may confuse "induction" with "deduction" because they look and sound similar. Remember: induction = from specific examples to a general rule; deduction = from a general rule to a specific conclusion.
Sinonime
generalization (Focuses on the end result (a broad statement) rather than the careful reasoning process; often used more critically.)
|
inductive reasoning (A near-equivalent phrase that explicitly names the type of thinking involved.)
Antonime
deduction (Deduction moves from general rules to specific conclusions, the opposite direction of induction.)

medical starting of childbirth
A hospital process where doctors make labor start using medicine or other medical methods.
Tipar de utilizare:
the induction of [labor] at [time]
Greșeală frecventă:
Learners may think "induction" here just means any start of labor. In medical English it usually means labor is started by doctors, not that it begins by itself. Also, this sense is almost always used in the phrase "induction of labor" or "labor induction."
Sinonime
labor induction (A more specific term that clearly says the induction is about childbirth.)
Antonime
spontaneous labor (Refers to labor that begins naturally, without medical induction.)

electromagnetic production of electricity
A physical process where a changing magnet field makes electricity in a nearby wire or metal.
Tipar de utilizare:
induction of [current/voltage] in [a conductor]
Greșeală frecventă:
Learners may confuse "induction" with "inductor" or use it to mean any electric effect. In physics, this sense of "induction" specifically describes current or voltage created by a changing magnetic field, not just any flow of electricity.
Sinonime
electromagnetic induction (More specific technical term; explicitly names the electromagnetic cause of the effect.)
Antonime
conduction (Conduction refers to transfer of electric charge or heat through a material, contrasted with the generation of current by induction.)

mathematical proof by induction
A way to prove a math rule is true for all whole numbers by proving it for the first number and then proving that if it is true for one number, it is also true for the next number.
Tipar de utilizare:
proof by induction on [a variable]
Greșeală frecventă:
Learners sometimes mix this mathematical sense of "induction" with the logical sense of induction from examples. In mathematics, "induction" almost always refers to the specific proof method "mathematical induction," not to reasoning from many examples.
Sinonime
mathematical induction (Standard full term for this proof technique; identical in technical use.)
Antonime
direct proof (A contrasting proof style that does not rely on an inductive step from one case to the next.)
