Forward tactical on grass stretch (5)
I believe the answer is:
along
'forward' is the definition.
(I've seen this before)
'tactical on grass stretch' is the wordplay.
'ALONG' is hidden within the letters.
But, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for along that I've seen before include "together" , "Beside - as groups often sing!" , "Throughout; onward" , "(Going) in company (with others)" , "With a forward motion: in accompaniment" .)
