Sheep first in pasture? It's not on the level (4)
I believe the answer is:
ramp
'not on the level' is the definition.
I can't judge whether this defines the answer.
'sheep first in pasture?' is the wordplay.
'sheep' becomes 'ram' (male sheep).
'first in pasture?' becomes 'p' (1st letter of 'pasture').
'ram'+'p'='RAMP'
'it's' is the link.
Can you help me to learn more?
(Other definitions for ramp that I've seen before include "Inclination - swindle" , "One's inclined" , "run around" , "Short slope" , "Sloping surface; swindle" .)
