What does eagre mean?
An eagre is a tidal bore: the striking natural phenomenon in which an incoming ocean tide pushes up against a river's current and forms a single steep wave that travels upstream. The word is used almost exclusively in British English and is particularly associated with the River Severn in western England, whose bore is one of the largest in the world and a popular attraction for sightseers and surfers alike. An eagre arrives suddenly and dramatically — often with an audible roar — making it both a spectacle and a hazard to boats caught unprepared on the water. In everyday modern usage the word has largely given way to the simpler term 'bore,' so 'eagre' survives mainly in regional writing, historical accounts, and literary description. Its exact origin is uncertain, though it has been linked to Old Norse and other Germanic sources, and variant spellings such as 'aegir' appear in older texts.
nounA tidal bore — a high wave that flows upstream from an estuary, caused by the incoming tide meeting a river's current. The term is used especially of the bore on the River Severn in western England.
- A tidal bore or abrupt flood tide moving up a river estuary, especially on the River Severn.
"Spectators lined the banks at dawn to watch the eagre surge up the Severn."
"The eagre swept up the estuary with a roar that could be heard long before the wave came into view."
"Old accounts describe farmers timing their crossings of the Severn to avoid the treacherous eagre."
Rarely pluralized, as the term usually refers to the specific phenomenon of a particular river.
"Travellers' journals of the eighteenth century describe the eagres of several English rivers."
Britain's most famous eagre can be surfed for miles — the Severn bore it names draws wave-riders who ride one wave for over half an hour.

Etymology of eagre
The origin of 'eagre' is uncertain, but it has commonly been connected to Old Norse 'áss' or related Scandinavian words for a stream or torrent, reflecting Norse influence in the regions where the word was recorded. It appears in English sources from around the early seventeenth century, applied specifically to the tidal bore of rivers such as the Severn and the Trent. Variant spellings including 'aegir' and 'eger' occur in older usage, underscoring the word's obscure history. It remains essentially confined to British English.
How eagre is actually used
Eagre is chiefly British and strongly associated with the River Severn, where the phenomenon is more commonly called the 'Severn bore' today. The word is literary and somewhat dated; 'bore' is the standard modern term. Spelling varies historically (also 'aegir', 'eger'), which reflects its uncertain origin.
