Likely for highly attractive sort to pick up student (8)
I believe the answer is:
probable
'likely' is the definition.
(similar in meaning)
'for highly attractive sort to pick up student' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'highly attractive sort' becomes 'babe' (I can't explain this - if you can you should give a lot more credence to this answer).
'to pick up' means one lot of letters goes inside another.
'student' becomes 'l' (as in L-plates for learner drivers).
'babe' enclosing 'l' is 'bable'.
'pro'+'bable'='PROBABLE'
Can you help me to learn more?
(Other definitions for probable that I've seen before include "Person most likely" , "on the cards" , "Likely to happen but not certain" , "Like to happen" , "Seeming to have a good chance of happening" .)
