Round his place oddly beginning to rage inside (9)
I believe the answer is:
spherical
'round' is the definition.
('spherical' can be similar in meaning to 'round')
'his place oddly beginning to rage inside' is the wordplay.
'oddly' indicates an anagram.
'beginning to' suggests taking the first letters.
'inside' means one lot of letters goes inside another.
The first letter of 'rage' is 'r'.
'his'+'place'='hisplace'
'hisplace' is an anagram of 'spheical'.
'spheical' placed around 'r' is 'SPHERICAL'.
(Other definitions for spherical that I've seen before include "Globular" , "Globe-shaped" , "Completely round" , "Ball-shaped" , "Ball shaped" .)
