Learner half-dead after going through dangerous act (7)
I believe the answer is:
student
'learner half-dead after going through dangerous act' is the definition.
I can't tell whether this defines the answer.
'learner half' is the wordplay.
'learner' becomes 'collegestudent' (college student is a kind of learner).
'half' indicates taking half.
'collegestudent' with half the letters taken is 'STUDENT'.
Can you help me to learn more?
(Other definitions for student that I've seen before include "Learner, pupil" , "One at university" , "A learner as at school" , "Undergraduate maybe" , "Trainee" .)
