Passport and driving licence? They are the basics for drive (3)
I believe the answer is:
ids
'the basics for drive' is the definition.
I can't judge whether this definition defines the answer.
'passport and driving licence? they' is the wordplay.
'passport' becomes 'id'.
'and' is a charade indicator (letters next to each other).
'driving licence? they' becomes 's' (I can't explain this - if you can you should give a lot more credence to this answer).
'id'+'s'='IDS'
'are' is the link.
Can you help me to learn more?
(Other definitions for ids that I've seen before include "Cards to identify the bearers, initially" , "Tory" .)
