Incline worker to suggest it's spreading, unchecked (7)
I believe the answer is:
rampant
'it's spreading unchecked' is the definition.
(I've seen this before)
'incline worker' is the wordplay.
'incline' becomes 'ramp' (synonyms).
'worker' becomes 'ant' (worker is a type of ant).
'ramp'+'ant'='RAMPANT'
'to suggest' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for rampant that I've seen before include "Fulminate" , "Spreading unchecked" , "running wild" , "Showing unrestrained growth" , "Unrestrained and violent" .)
