dimly (adverb), dimness (noun)
Dim dates back to before the year 1000. The Old English adjective dimm, and later the Middle English dim(me), meant ‘dark, gloomy or obscure.’ It can be traced back to the Proto-Germanic dimbaz, and is related to the Old Frisian dim, the Old Norse dimmr and the Old High German timber, all meaning ‘dark, black, or somber.’ There seems to be no relation to any word outside Germanic languages. The verb comes from the adjective and dates back to around the year 1200. Some linguists believe that it already existed in Old English, though all examples have been lost.
