Show proudly that dad's exceptionally dear (6)
I believe the answer is:
parade
'show proudly' is the definition.
'parade' can be an answer for 'show' (I've seen this before). I'm unsure of the 'proudly' bit.
'dad's exceptionally dear' is the wordplay.
'dad' becomes 'pa' (both can mean one's father).
'exceptionally' indicates anagramming the letters.
'dear' anagrammed gives 'rade'.
'pa'+'rade'='PARADE'
'that' is the link.
Can you help me to learn more?
(Other definitions for parade that I've seen before include "Public walk or march" , "Show (put on by soldiers?)" , "Row of shops, march" , "Public procession as on St Patrick's Day" , "Easter ___ , 1948 film with Judy Garland and Fred Astaire" .)
