Trainee programme opened up by Institution of Civil Engineers (10)
I believe the answer is:
apprentice
'trainee' is the definition.
(I've seen this before)
'programme opened up by institution of civil engineers' is the wordplay.
I cannot quite see how this works, but
'programme' could be 'app' (type of computer programme) and 'app' is present in the answer.
'engineers' could be 're' (Royal Engineers) and 're' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for apprentice that I've seen before include "Novice" , "Learner" , "student" , "Trainee" , "new worker" .)
