A capital way to go (5)
I believe the answer is:
ahead
'a capital way to go' is the definition.
I can't tell whether this definition defines the answer.
'a capital way to go' is the wordplay.
'a' becomes 'an'.
'capital' becomes 'head'.
'way' becomes 'n' (Compass direction - North).
'to go' suggests deleting specific letters.
'an'+'head'='anhead'
'anhead' with 'n' taken out is 'AHEAD'.
Can you help me to learn more?
(Other definitions for ahead that I've seen before include "likely to win?" , "In the leading position" , "Forwards" , "What's down the road" , "Forward - in front" .)
