12 meanings of instance

Practice

  1. 1
    examplenouncountable
    A case offered as an example or precedent; an illustrative example.

    The lawyer cited an instance from a previous trial to support her argument.

    His kindness was well known in town; one instance was the winter night he drove a stranded stranger two hours home.

    UsageVery common in for instance, which means for example. You give or cite an instance of something.

    Similarexample, case, illustration, precedent

    Note

    Older prose could use the word without an article, as something one gives. Robert Burton writes that Philostratus "gives instance in his friend Athenodorus," who, as Burton tells it, loved a woman at Corinth he had never seen. Where the "recurring case" meaning simply tallies occurrences, this one picks out a single case to illustrate or prove a point.

  2. 2
    occurrencenouncountable
    A particular occurrence of something that happens repeatedly in essentially the same way.

    Investigators logged dozens of instances of unauthorized access.

    Each instance of the glitch was reported to the support team.

    UsageUsually an instance of something: instances of fraud. In some instances is a careful way to say sometimes.

    Similarcase, occurrence, incident

    Note

    The everyday counting sense applies when the same kind of thing keeps happening: another instance of withdrawal, another instance of the general rule that human beings die. Each occurrence is essentially the same, so the word suits tallies and patterns rather than one striking example.

  3. 3
    occasionnounusually singular
    A particular occasion; the point or order in which something occurs.

    In the first instance, complaints go to the department head.

    The matter was settled by a court of first instance before any appeal.

    UsageMostly in set phrases: in the first instance (first, before anything else is tried) and in this instance.

    Similaroccasion, stage

    Note

    Matthew Hale's History of the Common Law of England, published in 1713, describes statutes drawn up "into the form of a law in the first instance" and only then assented to by both Houses and the King. Law keeps the same idea of order in court of first instance, the court that hears a case before any appeal.

  4. 4
    give examplesverbtransitive
    To give something as an example, or to offer examples, in support of a point or argument.

    To support her claim, she instanced three recent court rulings.

    Critics instance several films that broke box-office records.

    UsageTakes the example directly, with no preposition: she instanced three rulings. Mostly in argument and reports; cite is more common.

    Note

    A farmers' club speaker "instanced experiments" in The New-York Times of 1858, and E. M. Butler's study of Rilke speaks of "the poems which I have instanced." Cite says much the same thing. Instance stresses that what is mentioned is put forward as an example.

  5. 5
    computingnouncountable
    A specific occurrence of something created or instantiated, such as a running database or an object of a class in programming.

    The server spins up a fresh instance of the database for each client.

    Calling the constructor creates a new instance of the class.

    Similarobject

    Note

    Programming's word for one concrete realization of a template. The class is the pattern, each instance is a separate thing built from it, and the verb for making one is instantiate. The idea stretches to whole systems, such as a running database. Extra copies can be a bug: Bulka and Mayhew's Efficient C++ (1999) warns of compilers that wrongly create several instances of an inlined variable at run time.

Origin

Latin "instans" ("urgent") gave rise to "instantia," a noun for nearness and presence that could also mean perseverance, earnestness, or urgency; English borrowed the word through Middle French "instance." "Instant" shares the same root.
