Gold lining grand urinal bewildered maiden (9)
I believe the answer is:
inaugural
'maiden' is the definition.
(I know that maiden can be written as inaugural)
'gold lining grand urinal bewildered' is the wordplay.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'lining' is an insertion indicator.
'grand' becomes 'g' (G is short for grand as in a thousand).
'bewildered' indicates anagramming the letters.
'g'+'urinal'='gurinal'
'gurinal' anagrammed gives 'ingural'.
'au' going within 'ingural' is 'INAUGURAL'.
(Other definitions for inaugural that I've seen before include "It may be delivered" , "Marking the beginning of, eg, an institution" , "Of an opening ceremony" , "Maiden" , "Introductory" .)
