Incline towards? Most assuredly! (6)
I believe the answer is:
rather
'most assuredly' is the definition.
(thesaurus)
'incline towards?' is the wordplay.
I cannot quite understand how this works, but
'towards?' could be 'at' and 'at' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rather that I've seen before include "Quite; on the contrary" , "Infinite time" , "Slightly, more so than not (6" , "On the contrary; more precisely" , "On the contrary or to some extent" .)
