Meaning of suffix '-sex' in 'Sussex, Middlesex' [closed]

I know that Sussex and Middlesex are in England. It looks to me as if there is a pattern in names.

What does the suffix -sex mean? Where does it come from?


The -sex suffix is from Anglo-Saxon / Old English, with the actual meaning being "Saxon".

  • Sussex is essentially "South Saxon".
  • Middlesex is "Middle Saxon".
  • Essex is "East Saxon".
  • Wessex is "West Saxon".​​​​​​​

Most of the wiki pages for these places will have the toponymy definition.


The suffix originates from the word Saxon, which is derived from the German state of Saxony
