My current theory on Saxon Place Names
In 2000 I was looking at the place names around Hastings, which all appear to be Saxon, with a very few exceptions, and wondered what they meant.
My research lead me to conclude that this area was settled between the take over of Kent by Henghest and Horsa, and the take over of the South Downs area by Aelle, so around 465AD, and was settled by the Saxons.

As a lot of villages have similar snippets in their name and I wondered if each of these meant something, and that this in turn might mean that the settlement names described the use or surroundings of a place.
I am not a historian, so until 2026 I had not come across the Gelling-Cole Hypothesis, but this seems to fit well with my stuff. I have also in 2026 found an academic document written by Dr Robert Higgs from the 'The Journal of Coastal Research' which discusses sea levels in early Saxon times, this also fits my research.
So what could these snippets mean ??
My conclusions may seem surprising but please read Places containing the snippet æg meaning island before reading any other snippet pages as this explains the reason for the '4.5 metre line' described in other snippets.

| Our modern term island is derived from the Anglo Saxon æg land ▲ |
|---|
|
æg (pronounced 'ay') means island, and land means land, so æg land translates literally as 'island land' — land surrounded by water — and was probably originally pronounced 'ay land'. Over time this became 'island', with the silent 's' a later addition under the influence of the Latin insula.
From my research the following early Saxon name snippets are associated with islands.
- ending in eye - example Horse eye
From the Saxon - hors æg -meaning horse island - Pevensey Marsh
- ending in ey - example Horsey
From the Saxon - hors æg - meaning horse island - East Coast of Norfolk
- ending in ay - example Hilgay
From the Saxon - hyll æg - meaning hilly island - The Wash
- ending in et - example Thanet
From the Saxon - þegn æg - meaning thane's island - East Kent
- ending in ly - example Ely
From the Saxon - él æg - meaning the eel island - The Wash
- ending in ney - example Bardney
From the Saxon - barda en æg - meaning the people of the boat island - The Wash
- ending in sea - example Brightlingsea
From the Saxon - briht el aeng æg - meaning the people of the bright fort island - Essex
- ending in ye - example Rye
From the Saxon - úter æg - meaning the outer island - East Sussex
- ending in is - example Chatteris
From the Saxon - caefer æg - meaning insect island (probably a later name) - The Wash
- starting in eg - example Egham
From the Saxon - æg hamm - meaning the island in the valley
The term 'Isle' which is just a short form of 'Island' appears to be a later addition to the language as the early islands of Thanet and Oxney have had 'Isle of' attached to the original name, these must have been added some time after the original meaning æg of was lost.
It is likely that 'Chatteris' was a later name and may have originally been 'Chatter æg land', as it seems probable that the suffix is is of this later type .
| | Issues with these places being islands ▲ |

A significant number of places bearing æg names are now well inland — Ely sits in the middle of the Fens, Thanet is no longer an island, Chatteris is surrounded by farmland. This raises an obvious question: if these were genuine islands when they were named, what has changed?
The answer appears to lie in a dramatic fall in relative sea level since early Saxon times. The two pages linked below work through the evidence in detail for two separate areas — the Pevensey Levels in East Sussex, and the Wash in Eastern England. In both cases, the æg settlements only become true islands when the high tide level is raised by approximately 4 to 5 metres above its current position.
It is worth noting a complicating factor: both the Fens and the Pevensey Levels have been artificially drained over centuries, and the underlying peat has dried and shrunk as a result, lowering the land surface by roughly 2 metres in some areas. This means the true sea-level change may have been somewhat less than 4.5 metres — perhaps 2 to 3 metres — with land subsidence accounting for the remainder. Either way, the landscape in early Saxon times was dramatically more coastal than it appears today.

| | Implications of the above articles -> 4.5metre high tide ▲ |
|---|
The implication of the above two articles is that the high tide level in Later Roman/Early Saxon times was about 4.5 metres a little higher than today.
There is a possibility that the high tide level rise was only 2 - 3 metres higher as the areas I have used for the analysis, the Fens and the Pevensey Marshes have been drained over time and therefore the land has sunk by about 2 metres due to the drying out of the underlying peat.
However, the 4.5 metre mark would then show the high tide mark in these areas.

Several independent lines of evidence point to the same conclusion:
Roman roads that just terminate — A number of Roman roads in Britain and northern Gaul end abruptly at locations that would have been coastal ports if the tidal level was 4 to 5 metres higher. The roads were not abandoned unfinished; their destinations have simply been swallowed by centuries of coastal change.
Sea level changes over the last 2000 years — A broader look at the evidence for changing sea levels across the period from Roman times to the present day.
The 2026 Journal of Coastal Research paper by Dr Roger Higgs — Geological excavation at Pevensey Castle found 5th-century tidal mud within the defensive ditch at a level more than 2 metres above the fort's original foundations. The paper documents a rapid relative sea-level rise of approximately 4 metres occurring within roughly 70 years, centred on 430–500 AD. This is direct physical confirmation of what the place-name analysis independently suggests.

The æg place names of England are not merely curiosities of etymology. They are a record, frozen into the landscape, of a coastline that looked fundamentally different from the one we know today. Settlements named as islands were genuine islands — not poetic descriptions, not metaphors, but practical observations made by people living at the water's edge.
The flood modelling, the Roman road evidence, the Domesday records, and now the geological data from the 2026 Journal of Coastal Research paper all point to a high tide level approximately 4 to 5 metres above its current position in early Saxon and late Roman times. Every place name on this page is a small piece of that evidence.
If you are exploring the place names in your own area and find an æg name that now sits well inland, it is worth checking the local topography at the 4 to 5 metre contour — you may find you are standing on what was once a tidal island.
