Go green in a weird way and articulate why (6)
I believe the answer is:
'go green in a weird' is the definition.
'energy' can be an answer for 'go' (I've seen this before). I am not certain of the 'green in a weird' bit.
'way and articulate why' is the wordplay.
'way' becomes 'e' (Compass direction - East).
'and' becomes 'n' (common abbreviation for 'and').
'articulate' becomes 'erg' (I can't justify this - if you can you should give a lot more credence to this answer).
'why' becomes 'y'.
Can you help me to learn more?
(Other definitions for energy that I've seen before include "Healthy capacity for vigorous activity" , "Vigour, spirit" , "Power - drive" , "It's measured in joules or ergs" , "Gusto" .)
