Tommy's training? (7,8)
I believe the answer is:
private practice
'tommy's training?' is the definition.
I can't judge whether this definition defines the answer.
'tommy's training?' is the wordplay.
'tommy' becomes 'private' (informal term for a British soldier).
'training?' becomes 'practice' (practice is a kind of training).
'private'+'practice'='PRIVATE PRACTICE'
Can you help me to learn more?
(Other definitions for private practice that I've seen before include "no NHS concern" , "professionally lucrative?" , "Basic army training" .)
