Initial deal that comes through personal experience (5,4)
I believe the answer is:
first hand
'comes through personal experience' is the definition.
I can't tell whether this definition defines the answer.
'initial deal' is the wordplay.
'initial' becomes 'first' (similar in meaning).
'deal' becomes 'hand' (synonyms).
'first'+'hand'='FIRST-HAND'
'that' is the link.
Can you help me to learn more?
(Other definitions for first hand that I've seen before include "directly" , "Direct" , "leading seaman?" .)
