Green pipe going across road area (7)

Ross

I believe the answer is:

verdant

I'm a little stuck... Click here to teach me more about this clue!

'green' is the definition.
(I've seen this before)

'pipe going across road area' is the wordplay.
'pipe going' becomes 'vent' (I can't explain this - if you can you should believe this answer much more).
'across' indicates putting letters inside.
'road' becomes 'rd' (abbreviation).
'area' becomes 'a' (maths abbreviation).
'rd'+'a'='rda'
'vent' placed around 'rda' is 'VERDANT'.

Can you help me to learn more?

(Other definitions for verdant that I've seen before include "Unsophisticated" , "Rather green" , "Green like grass or fields" , "Having green growth" , "Covered with lush green grass or vegetation" .)
