--(I)-J-R-Y
looks like AUTHORITY:author+rit (Fr.for is laughing)+ y (last of poppy)--but why 2 x r?
Then there's POSTERITY=seed,but why poste,exc.that you write "Y.t." in a letter of course.Sorry,probably confused you more than ever!
Got it - Jequirity!
It means 'seed' - I got it because I tried to fit in 'qui'('who') then realised I could add 'je'('yours truly'/me/I).The 'rit' is greedykite's + the 'y' is from 'poppy'. Done!
