eunoia

That must really eunoia, mollusque, that you can't find more citations for this word.

*ducks to avoid objects hurled at head*

Sometimes said to be the shortest English word with all the vowels. However, I haven't been able to find instances where "eunoia" is used without italics or without its definition appended ("goodwill" or "benevolence"). So it seems not be naturalized in English; it is a Greek word discussed in English works.

Another meaning for eunoia is found in a few dictionaries of psychology or medicine: "the healthy mind" or "alertness of mind and will". I haven't found this sense used outside of dictionaries.

my hypothesis:

eu- 'well, good'

"noia" = nous + -ia (as in paranoia)

where nous means 'mind, intellect'
and -ia is a noun suffix (found in anemia and phobia)

(all greek)
