Pronunciation: [ˈiːɡə] (IPA) 
The word "eagre" is pronounced as /iːɡə(r)/ and refers to a tidal bore, a large wave caused by the incoming tide of a river or narrow bay. The spelling of this word can also be seen as "eager" in some regions, which is pronounced as /iːɡə(r)/. The origin of this word is from the Old English word "ecg" meaning "edge" or "point" and was later combined with the word "ær" meaning "mud" to create "egær," eventually evolving into the word "eagre."
Eagre, also spelled as bore or aegir, refers to a tidal phenomenon characterized by a high and powerful oceanic wave that travels upstream in certain rivers or estuaries. It occurs when a large volume of water is pushed against the current by the incoming tide, creating a noticeable wave that can sometimes reach impressive heights and speeds.
The eagre is typically a result of the convergence of multiple factors. It occurs most commonly in rivers with a narrow and shallow estuary, combined with a large tidal range and a strong incoming tide. The shape and topography of the riverbed can also play a role in amplifying the strength and height of the wave.
The word "eagre" is believed to have originated from the Old Norse term "age," which means "fright" or "terror." This is because the eagre can be an awe-inspiring sight, especially as it surges against the normal flow of the river. It often attracts the attention of locals and tourists alike.
While the eagre is generally considered a natural phenomenon, it can have both positive and negative effects. On one hand, it can contribute to the ecological balance of estuaries by flushing out stagnant water and promoting the exchange of nutrients. On the other hand, it can also cause flooding and erosion along the riverbanks, particularly in areas with poor infrastructure or inadequate flood defenses.
Overall, the eagre is an impressive and unique occurrence in the natural world, showcasing the power of tidal forces and their impact on river systems.
The word "eagre" has its origins in Old English, where it was spelled "ēagor" or "ēgor". It is derived from the Old Norse word "Aegir", which referred to the Norse god of the sea. Over time, the word developed various spellings and forms in different regions, eventually settling as "eagre" in English. It has been used to describe a tidal bore or a tidal wave, particularly in the estuary of the River Trent in England.
