Wise person, I’ll see you shortly (5)
I believe the answer is:
solon
'wise person i'll' is the definition.
I can't judge whether this definition defines the answer.
'see you shortly' is the wordplay.
'see you' becomes 'so long' (I've seen this before).
'shortly' means to remove the last letter.
'solong' with its last letter removed is 'SOLON'.
Can you help me to learn more?
(Other definitions for solon that I've seen before include "Sage" , "Athenian statesman, one of Seven Wise Men" , "Law maker" .)
