August the first on road in San Diego on tour? (9)
I believe the answer is:
grandiose
'august' is the definition.
(thesaurus)
'first on road in san diego on tour?' is the wordplay.
'first on' says to take the initial letters.
'in' means one lot of letters goes inside another.
'on tour?' indicates an anagram (letters tour or travel around).
The first letter of 'road' is 'r'.
'san'+'diego'='sandiego'
'sandiego' anagrammed gives 'gandiose'.
'r' inserted inside 'gandiose' is 'GRANDIOSE'.
'the' acts as a link.
(Other definitions for grandiose that I've seen before include "affected" , "Impressive, magnificent" , "Bombastic" , "Planned on a magnificent scale" , "Ridiculously impressive or imposing" .)
