Raised support, quietly elated about recruiting son (8)
I believe the answer is:
pedestal
'raised support' is the definition.
(raised platform or support)
'quietly elated about recruiting son' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'about' is an anagram indicator.
'recruiting' means one lot of letters goes inside another (inserted letters are recruited into the word).
'son' becomes 's' (genealogical abbreviation for son).
'elated' is an anagram of 'edetal'.
'edetal' placed around 's' is 'edestal'.
'p'+'edestal'='PEDESTAL'
(Other definitions for pedestal that I've seen before include "Architectural support or base" , "Base supporting column" , "Base on which something is mounted" , "Base supporting a statue" , "Support for bust" .)
