Admire power contained in secret explosive? (7)
I believe the answer is:
respect
'admire' is the definition.
(admire can mean to respect)
'power contained in secret explosive?' is the wordplay.
'power' becomes 'p' (symbol in physics).
'contained in' means one lot of letters goes inside another.
'explosive?' is an anagram indicator (I've seen 'explosive' mean this).
'secret' anagrammed gives 'resect'.
'p' put inside 'resect' is 'RESPECT'.
(Other definitions for respect that I've seen before include "Admiration felt for another's good qualities" , "Have high regard for sceptre" , "Treat with consideration" , "Look up to" , "Regard, deference" .)
