Definition
A Latin term from Roman and civil law meaning "to build upon" or "to erect a structure on land." In its legal application, *edificare* refers to the act of constructing a building or other permanent structure, particularly as that act affects the rights of landowners, neighbors, and those with competing interests in the soil or adjacent property.
The term appears principally in discussions of Roman law doctrines governing the rights and obligations arising from construction — including who may build, where, how high, and what remedies exist when building encroaches upon another's rights. It is the root concept underlying several specific Roman law actions and interdicts concerned with building activity, structural interference with light and air, and encroachment.

Common Language
Modern common usage (Wiktionary): The English verb "edify" descends from the same Latin root and carries the sense of moral or intellectual improvement — to uplift or instruct. The noun "edifice" survives in ordinary English meaning a large or imposing building.
Historical common usage (Webster's 1913): Webster's traces "edify" to the Latin *aedificare* (to build), noting the English word had already shifted entirely toward the metaphorical sense of spiritual or moral building up. "Edifice" retained the physical meaning of a substantial structure or building.
The gap between common and legal usage is significant. By 1913, the English language had almost entirely abandoned the physical construction meaning of "edify" in favor of the metaphorical sense. Legal and civil law sources, by contrast, use *edificare* in its original, literal sense — the physical act of building — which is wholly distinct from the moral connotation English speakers associate with the cognate term.

Why It Matters in Research
Researchers encountering *edificare* in historical legal sources are almost always working in one of two contexts: (1) treatises or digests of Roman law, or (2) civil law commentaries — particularly those of the Spanish, French, or Scottish traditions — that imported Roman building-law doctrine into municipal or property law discussions.
The primary research trap is terminological drift. English-language legal dictionaries often translate or gloss *edificare* briefly, if at all, because the term functions more as a root concept than as a standalone doctrine in common law systems. Researchers using common law sources will rarely encounter the term directly; it surfaces most in translations of Justinian's Digest, in civilian property treatises, and in comparative law scholarship addressing servitudes, nuisance, and neighbor relations.
The doctrinal significance of *edificare* in Roman law was substantial. The *operis novi nuntiatio* (protest against new work) and the interdict *quod vi aut clam* both operated in part as responses to unauthorized *edificare* on another's land or in violation of servitudes. Researchers tracing the history of building restrictions, light-and-air easements, or construction-related nuisance doctrine will find *edificare* a useful index term when working through civilian sources.
Cross-corpus alert: In Louisiana, Quebec, and other mixed civil-common law jurisdictions, concepts derived from Roman building law — including restrictions on *edificare* — were absorbed into codified property law. Researchers working in those jurisdictions should check both civilian commentaries and the applicable civil code provisions on servitudes and predial obligations, where the underlying doctrine often survives even when the Latin terminology does not.

Historical Dictionary Support
Black's Law Dictionary treats *edificare* as a Roman law term and defines it in substance as the act of building or erecting a structure. The entry is compact and primarily serves as a bridge term connecting the reader to related Roman law doctrines rather than as a freestanding doctrinal entry.
The historical dictionaries reflect a consistent understanding that *edificare* was less a legal rule than a legal fact — the building act itself — from which various rights, obligations, and remedies flowed depending on circumstances. Where the sources diverge is in how much doctrinal context they supply: older civilian-inflected dictionaries and glossaries tend to situate the term within the framework of Roman interdicts and actiones, while common law dictionaries treat it as a Latin gloss requiring minimal elaboration.
What the historical dictionaries largely omit is any treatment of how *edificare* doctrine was received — or not received — into common law systems. The common law developed its own vocabulary for building-related disputes (nuisance, trespass, easements of light) without inheriting the Roman conceptual architecture intact. This gap means that researchers cannot assume continuity of doctrine simply because a Roman-law concept was known; they must trace separately how each jurisdiction addressed the underlying problem.

Jurisdictional Note
The term and its associated doctrines have most direct relevance in civil law jurisdictions and mixed systems. In Louisiana and Quebec, codified servitude and property law retains structural echoes of Roman building-law principles. In common law jurisdictions, the doctrinal functions of *edificare* have been absorbed into nuisance, trespass, and easement law under different terminology.
