English Vocabulary for Archaeologists: 50 Essential Terms

An artefact is a portable object made or modified by humans — a pot sherd, a coin, a stone tool — that can be lifted and taken to a laboratory for study. A feature, by contrast, is non-portable: it is part of the site itself, such as a posthole, a hearth, a ditch, or a wall. You cannot remove a feature without destroying it, so features are recorded in place through drawing, photography, and written notes. Understanding this distinction is fundamental because the two are handled and documented in completely different ways during an excavation.

In archaeological English, “sherd” specifically means a fragment of pottery or ceramic, while “shard” refers to a broken piece of glass. The two words share an origin but have become specialised. Using “sherd” correctly signals that you know the discipline's conventions. You will also encounter compound terms like “rim sherd” (a fragment from the top edge of a vessel) and “body sherd” (a piece from the main wall). Getting these terms right matters in find catalogues, where consistency is essential for later analysis.

“Terminus post quem” is a Latin phrase meaning “the limit after which,” and it refers to the earliest possible date a deposit could have formed. For example, if a layer contains a coin minted in AD 320, the layer cannot have been deposited before that year — so AD 320 is the terminus post quem. Its opposite is “terminus ante quem” (“the limit before which”), the latest possible date. These phrases are used constantly in dating discussions, and although they are Latin, they are standard working vocabulary in English-language archaeology.

The passive voice keeps the focus on the evidence and the site rather than on the individual excavator, which suits the objective tone of scientific reporting. Writing “the pit was excavated in 0.1m spits” emphasises the method and the feature, whereas “I excavated the pit” draws attention to the person. The passive also allows you to describe processes without needing to name who carried them out, which is useful in large team projects. While some modern guidance encourages a little more active voice for clarity, the passive remains the dominant register in formal excavation reports and academic journals.

Relative dating establishes the order of events — which find or layer is older or younger — without giving specific years. The law of superposition and typology are relative methods. Absolute dating, sometimes called chronometric dating, provides an actual age in calendar years or a measurable range; radiocarbon dating and dendrochronology are the best-known examples. In practice, archaeologists combine the two: relative methods build the framework of a site's sequence, and absolute methods anchor that sequence to real dates. Knowing which term applies prevents confusion when reading or writing about a site's chronology.

A context is the smallest unit of stratigraphy — a single deposit, cut, or surface that represents one archaeological event. Each context is given a unique number and recorded on its own sheet describing its colour, composition, finds, and relationships to neighbouring contexts. The fill of a pit is one context; the cut that created the pit is another; the layer the pit was dug into is a third. This single-context recording system, widely used in British archaeology, allows the entire site to be reconstructed later from the paperwork, even after the deposits themselves have been removed.

The most efficient approach is to learn words in topic clusters tied to real activities, exactly as fieldwork groups them. Pair each term with an image or a memory of seeing it on site, since visual association is far stronger than abstract definitions. Learning the Latin and Greek roots common in archaeology — strat-, chron-, litho-, paleo- — lets you decode many unfamiliar words. Reading short journal abstracts exposes you to the vocabulary in its natural academic context, and keeping a personal glossary of new terms you meet on a dig consolidates them. Regular spaced review, for example with flashcards, secures long-term retention.

An assemblage is a group of artefacts found together in the same context or deposit, treated as a unit for analysis. For example, all the pottery, bone, and metalwork recovered from a single rubbish pit form one assemblage. The term is useful because objects found together can be studied as a group to understand activity at a particular moment. Archaeologists often speak of a “ceramic assemblage” or a “lithic assemblage” when focusing on one material. The concept is central to interpretation, since the composition of an assemblage can reveal diet, trade, status, or function.

The difference is simply British versus American English. British and Commonwealth archaeology uses “artefact,” while American archaeology uses “artifact.” Both are correct; what matters is consistency within a single document and following the house style of your institution or journal. The same regional variation affects other archaeology vocabulary, such as “metre” versus “meter” for measurements and “catalogue” versus “catalog.” If you are working internationally, check which standard your project follows at the outset and apply it throughout your records and reports.

Provenance is the recorded origin and find-spot of an object — where it was found, in which context, and the chain of documentation that establishes this. Provenance is critically important because an artefact without it loses most of its scientific value: it cannot be securely dated by association, and its meaning is uncertain. Provenance also has ethical and legal dimensions, since objects without documented origins may have been looted or illegally exported. In American usage you may also see the related term “provenience,” which refers specifically to the three-dimensional location of a find within a site.
