Prepare oneself for, in the wake of (5)
I believe the answer is:
train
'prepare oneself' is the definition.
(I've seen this in another clue)
'in the wake of' is the wordplay.
I cannot really see how this works, but
'in' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
The remaining letters 'ra' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for train that I've seen before include "Public transport on the railway" , "Suite; give practice (in)" , "Locomotive plus carriages" , "Following" , "Coach - string of coaches" .)
