Hi a new word is tepor - listed in onelook under 8 dictionaries. Just love this puzzle!!
Jenny, I don't know whether you're Cleverjen or jenii, or someone else entirely, but you uttered the secret pass-phrase ("love this puzzle"), so your suggestion deserves to be taken seriously.
It seems
tepor is an old word for the quality of being tepid - more commonly
tepidity, or
tepidness. Onelook.com does have links to eight dictionaries that list the word, but quite a few of them seem to have taken it from the same source - Webster's 1913 dictionary. I also found it in the Shorter Oxford, where it is marked as obsolete.
So I think we can say it's not in widespread current use - but the same could no doubt be said of thousands of the words already in our list. So I'll add
tepor to the list. Thanks for the suggestion Jenny.
