Asleep when roused in delight (6)
I believe the answer is:
Here is my best explanation:
'delight' is the definition.
('please' can be a synonym of 'delight')
'asleep when roused' is the subsidiary indication.
'asleep' anagrams to 'please'.
However, I am not sure how the anagram is indicated.
'in' is the link.
(Other definitions for please that I've seen before include "Make glad, being asleep", "If you'd be so kind?", "Be good enough to", "Give satisfaction to", "Delight, gladden", "Beatles song (request to oblige?)", "Gratify or ask nicely", "See 10 Across", "Entertain" and "Gratify as by a sleep".)
