My first reaction as a German was a connection between "dungi" and the German noun "Dung" also meaning "dung" in English. I never heard someone using the word "dingen".
I think there is something oddly appropriate about the word for hire resembling the word dung.
It also resembles to danish word "dunke" which is slang for "to f***". - A way to convince the boss to hire you.
Idk... I'm looking at the etymology for "dungeon"and it lists the German word "Tunk", meaning: “manure or soil covered basement, underground weaving workshop”. I kid you not. https://en.wiktionary.org/wiki/dungeon#Etymology
"Both the Frankish and Old English words derive from Proto-Germanic dungijǭ (“an enclosed space; a vault; bower; treasury”), from Proto-Indo-European dʰengʰ- (“to cover”), and are related to Old Saxon dung (“underground cellar”), Middle Dutch donc (“underground basement”), Old High German tung (“underground cellar; an underground chamber or apartment for overwintering”) (whence German Tunk (“manure or soil covered basement, underground weaving workshop”)), Old Norse dyngja (“a detached apartment, a lady's bower”) (whence Icelandic dyngja (“chamber”)). See also dung, dingle."
Well... According to Wiktionnary, it from the obsolete german word "dingen", of the same meaning. It seems to cognate somehow with the english word "thing" (and the german word "Ding").
German "dingen" and English "thing" are both from the Proto-Germanic word *þingą, which means an "assembly". Then it is a complicated story, you should look by yourself....
"Dongeon", however, cognate with the english word "dung". You probably can guess how.
haha, yep, it was interesting to learn that dungeon and dung are related terms. Interesting about dingen, ding and thing. I can see how a word meaning "assembly" would eventually lead to the meaning of "work" and then "to hire". Really fascinating how language evolves!
Actually the etymology goes differently, even more roundabout. Ding goes from 'assembly' to something like 'court hearing', from which the verb "dingen" 'to plea, to plead' is derived. This then goes to the meaning 'make an offer (to buy)', and thus 'make an offer (to hire)'.
