Freda's silly to hide money from him (6)
I believe the answer is:
alfred
'him' is the definition.
'freda's silly to hide money' is the wordplay.
'silly' is an anagram indicator.
'to hide' indicates putting letters inside.
'money' becomes 'l' (L can mean 'pounds').
'freda' is an anagram of 'afred'.
'afred' enclosing 'l' is 'ALFRED'.
'from' is the link.
(Other definitions for alfred that I've seen before include "Former king" , "Ninth century king of Wessex" , "Chap" , "English-born film director" , "King after Ethelred" .)
