Lid for jars, ornate (6)
I believe the answer is:
florid
'ornate' is the definition.
(thesaurus)
'lid for jars' is the wordplay.
'jars' indicates an anagram (the letters must be shocked or jarred).
'lid'+'for'='lidfor'
'lidfor' with letters rearranged gives 'FLORID'.
(Other definitions for florid that I've seen before include "Excessively ornate" , "Using unusual words" , "Overly ornate" , "Flushed with red" , "Over-elaborate" .)
