Thus, alternatively, embracing permitted source of legal aid (9)

I believe the answer is:
solicitor
'source of legal aid' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'thus alternatively embracing permitted' is the wordplay.
'thus' becomes 'so' (synonyms).
'alternatively' becomes 'or'.
'embracing' is an insertion indicator.
'permitted' becomes 'licit' (licit means allowed or permitted).
'so'+'or'='soor'
'soor' going around 'licit' is 'SOLICITOR'.
Can you help me to learn more?
(Other definitions for solicitor that I've seen before include "Legal officer" , "court officer" , "Cake topping" , "Law practitioner" , "beggar" .)
