We have to admit that this is a made-up word, but it has Anglo-Saxon roots.
“Paethas” means “paths”. The “ae” is the Old English letter Ash, which is pronounced like the “a” in “hat”. So you can see that when our Anglo-Saxon ancestors talked about paths, they used a word that sounded very similar to ours. The language hasn’t changed very much.
“Geo” is a suffix that is applied to a number of words. For example, “Geomann” means “a man or person in the past”, and “Geolean” means “a reward for a past deed”.
So if the residents of Anglo-Saxon Lyminge had ever needed to talk about pathways to the past, they might just have talked about geopaethas.
