No ! But you’re welcome to look it up in an English dictionary just to confirm it. I’d love to know how you came up with this non existent word.

Conferrable exists ... But I am unsure if you can apply any affix before it... "Im" "in" "un" "ir" or any other affix... because you cannot un bestow an honour that has been awarded... You can only take the honour away. Which is called "forfeiture" ---- "The honour conferred upon you will be/has been forfeited"... Bestowed is the common word that people would mostly use.... "the honour bestowed upon you"

It looks like an English word, and it quacks like an English word. But it isn't an English word =? How would we use this word if it did exist? "You may not consult with your teammates, as the questions in the next round are inconferrable" "The title Wanker of the Decade was deemed inconferrable by Ofcom"
