Time of pageantry (3)
I believe the answer is:
age
'time' is the definition.
(an age is a period of time)
'of pageantry' is the wordplay.
'of' indicates a hidden word.
'AGE' is hidden within 'pageantry'.
(Other definitions for age that I've seen before include "Period of time" , "Years since birth" , "Era; grow old" , "Years lived so far" , "16/18 [INDUSTRIAL REVOLUTION]" .)
