Reveal most of ugly dive has to be revamped (7)
I believe the answer is:
divulge
'to be revamped' is the definition.
I can't judge whether this defines the answer.
'reveal most of ugly dive' is the wordplay.
'reveal' indicates an anagram.
'most of' means to remove the last letter.
'ugly' with its last letter taken away is 'ugl'.
'ugl'+'dive'='ugldive'
'ugldive' is an anagram of 'DIVULGE'.
'has' is the link.
Can you help me to learn more?
(Other definitions for divulge that I've seen before include "Make known (a secret)" , "Make public" , "Disclose, give away" , "Disclose (a secret)" , "Make (secrets) known" .)
