Definition
A Latinized place-name appearing in historical legal documents to denote a specific geographic location in England. The term is a Latinized or Romano-British toponym used in medieval legal instruments, charters, grants, and ecclesiastical records to identify a place — most likely associated with the river Alne in Gloucestershire, given its proximity to the related form ALAUNUS (the Latinized name for that river). The suffix -dunum is a common Romano-Celtic element meaning a fortified hill or settlement, so ALAUNODUNUM designates, in essence, the fortified place or settlement on the Alne.
Why It Matters in Research
Researchers encountering ALAUNODUNUM in primary sources face the core challenge of all historical place-name research: identifying which modern location a Latinized toponym corresponds to, and confirming that the identification is correct for the specific document and period under examination. Several practical cautions apply.
First, Latinized place-names were not always applied consistently. A scribe in one century might use ALAUNODUNUM to refer to a settlement that a scribe in another century called something else entirely, and different authorities have proposed different modern equivalents for many Romano-British names.
Second, the connection to the river Alne in Gloucestershire is supported by the related entry ALAUNUS in Burrill, but researchers should not treat this as settled without consulting dedicated onomastic and historical-geographic reference works. The Alne runs also through Warwickshire, and place-name authorities have not always agreed on which settlement should bear the -dunum form.
Third, in legal documents — particularly medieval charters, land grants, conveyances, and ecclesiastical instruments — accurate identification of a place-name can be dispositive. Misidentifying ALAUNODUNUM could lead a researcher to the wrong county, hundred, or manor entirely, with cascading errors in title chains or boundary disputes.
Fourth, Law Mind corpus researchers should cross-check any document using ALAUNODUNUM against companion place-name forms (ALAUNUS, and nearby entries in Burrill) as well as against external resources such as the English Place-Name Society volumes for Gloucestershire and Warwickshire, and Ekwall's Concise Oxford Dictionary of English Place-Names, which document Romano-British and medieval Latin forms systematically.
Historical Dictionary Support
Burrill's Law Dictionary is the sole historical shelf source providing this entry, and its treatment is spare: ALAUNODUNUM appears in a cluster of Latinized place-names with terse modern equivalents, without elaboration on legal context or documentary usage. The companion entry ALAUNUS identifies the river Alne in Gloucestershire as the referent, which is the primary evidence linking ALAUNODUNUM to that region.
Burrill's entries in this category function less as legal definitions and more as a finding aid — a decoder ring for readers encountering unfamiliar Latin toponyms in old English legal documents. No other standard historical law dictionary (Bouvier, Black, Tomlin, Jacob) appears to carry this term, making Burrill the only direct shelf authority. Researchers should note that Burrill's place-name identifications, while generally reliable for their era, predate modern systematic place-name scholarship and should be verified against current onomastic sources before being relied upon in any title or boundary matter.
Jurisdictional Note
As a place-name, ALAUNODUNUM has no operative legal meaning independent of the document in which it appears. Its relevance is confined to English legal history, primarily to documents originating in or concerning the west of England.
