Be successful with peg leg initially (2,4)
I believe the answer is:
do well
'be successful' is the definition.
I can't tell whether this definition defines the answer.
'with peg leg initially' is the wordplay.
'with' says to put letters next to each other.
'peg' becomes 'dowel' (a dowel is a wooden peg).
'initially' says to take the initial letters.
The first letter of 'leg' is 'l'.
'dowel'+'l' is 'DO WELL'.
Can you help me to learn more?
(Other definitions for do well that I've seen before include "boom" , "Flourish" .)
