Join to get a bit of basic education during May (5)

I believe the answer is:

marry

I'm a little stuck... Click here to teach me more about this clue!

'join' is the definition.
(I know that marry is a more specific form of the action unify)

'a bit of basic education during may' is the wordplay.
'a bit of basic education' becomes 'rr' (I can't justify this - if you can you should give a lot more credence to this answer).
'during' indicates putting letters inside.
'rr' placed inside 'may' is 'MARRY'.

'to get' is the link.

Can you help me to learn more?
