Observes one's wishes (7)
I believe the answer is:
regards
This could be a double definition.
'observes' is the first definition.
(I've seen this before)
'one's wishes' is the second definition.
'regards' can be an answer for 'wishes' ('regard' can be a synonym of 'wish'). I'm not sure about the 'one's' bit.
Can you help me to learn more?
(Other definitions for regards that I've seen before include "Heeds" , "Contemplates" , "what to put before signature?" , "Gazes at; compliments" , "Observes" .)
