6 meanings of artefact

Practice

  1. 1
    historical objectnouncountable
    An object such as a tool, weapon or ornament that is valued for what it reveals about the past, especially one found at an archaeological dig or held in a museum.

    Archaeologists recovered more than two thousand artefacts from the Iron Age settlement, including brooches and spearheads.

    Each artefact is photographed and labelled before it leaves the trench.

    Similarfind, relic, antiquity

    Note

    On a dig the word is kept narrow: an artefact is something people made or altered that can be lifted from the ground. Seeds, pollen and animal bones that nobody shaped are ecofacts, and fixed traces such as post holes are features, so a site report keeps the three apart. Museums stretch the word further, sometimes to any object in the collection, made by people or not.

  2. 2
    man-made objectnouncountable
    Any object made or shaped by human hands or human effort; in some uses, an object shaped by any maker, such as a tool made by an animal.

    The researchers treated the booking website as a designed artefact, studying how customers moved through it.

    Designers spend hours watching how people handle everyday artefacts such as kettles and door handles.

    Similarobject, item

    Note

    The British spelling is artefact, while American writers use artifact, so the two forms can sit side by side in one bibliography. Both go back to Latin arte, "by skill", and factum, "thing made". That origin is why the word stresses the making: a kettle or a website is an artefact because someone designed it.

  3. 3
    media distortionnouncountable
    A noticeable distortion in an image, video or audio recording, produced by lossy compression, another imprecise processing method, or physical interference while the signal is captured.

    Streaming at a low bit rate leaves compression artefacts in dark scenes, where the shadows break up into blocks.

    The radiologist recognised the bright streak as an artefact caused by the patient's metal filling.

    Similardistortion

    Note

    Compression artefacts are named by how they look: blocking, where the picture breaks into visible squares, and mosquito noise, a shimmer of dots around edges in compressed video. In X-rays and scans the word covers streaks or shadows caused by metal or by movement, which can resemble disease and have to be recognised before the image is read.

  4. 4
    product of ideasnouncountable
    Something regarded as the product of human action or thought rather than as a natural or built-in part of things.

    Many borders in the region are artefacts of colonial treaties rather than natural divisions between peoples.

    The critic argued that the notion of a normal childhood is a cultural artefact shaped by the Victorians.

    UsageUsually an artefact of whatever caused it: an artefact of colonial rule. Also a cultural artefact.

    Similarproduct, construct, creation

    Note

    Calling something an artefact in this way is often a quiet argument that it is neither natural nor inevitable. The phrasing comes close to the experimenter's meaning, where a result is blamed on the method rather than on the thing being studied.

  5. 5
    false resultnouncountable
    A result or feature that comes from the way something was studied, tested or prepared, such as the method, the equipment or the treatment of a specimen, rather than from the thing itself.

    The apparent rise in cases may simply be an artefact of the new, more sensitive test.

    Researchers warned that the gap between the two groups could be a statistical artefact rather than a real difference.

    UsageUsual phrases: a statistical artefact, an artefact of the method or the test.

    Note

    A word scientists use as a warning: the result is really there on the screen or the slide, but it belongs to the method, not to the object. Biologists apply it to structures seen under the microscope that appear only because a specimen died, was prepared or was treated with chemicals, and were never there in the living cell.

  6. 6
    nouncountableabbreviationellipsis
    Short for build artifact: one of the files a compilation process produces for deployment and use.

    The pipeline keeps each artefact from the nightly build for thirty days.

    Before the release, she checked that the artefacts on the server matched the ones the testers had signed off.

    Note

    The shortened form software engineers use once the setting is clear: a pipeline publishes its artefacts, a release ships them, and build drops away. It is countable and usually plural, since one compilation can leave several deployable files behind. Here an artefact is the wanted product of the work, not a flaw, so it is not to be confused with the compression distortion that spoils an image or a sound file.

Origin

English took it from Italian artefatto, which joins two Latin words. One is arte ("by skill"), the ablative of ars ("art"); the other is factum ("thing made"), from facio ("to make, do").
