Assemble around snake biting queen consort (11)

I believe the answer is:
collaborate
'assemble' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Maybe there's a link between them I don't understand?
'around snake biting queen consort' is the wordplay.
'around' indicates putting letters inside.
'snake' becomes 'boa' (boa constrictor, type of snake).
'biting' means one lot of letters goes inside another (some letters bite or swallow others).
'queen' becomes 'r' (abbreviation for regina, e.g. in ER ).
'consort' becomes 'collate' (I can't explain this - if you can you should give a lot more credence to this answer).
'boa' enclosing 'r' is 'bora'.
'bora' inserted within 'collate' is 'COLLABORATE'.
Can you help me to learn more?
(Other definitions for collaborate that I've seen before include "Work together" , "Work jointly" .)
