Toadies engender a feeling of revulsion (6)
I believe the answer is:
creeps
This might be a double definition.
'toadies' is the first definition.
(I've seen this before)
'feeling of revulsion' is the second definition.
(I've seen this before)
'engender a' acts as a link.
This may not be correct. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for creeps that I've seen before include "'Tomorrow, and tomorrow, and tomorrow / . . . . . . in this petty place from day to day' (Macbeth)" , "treads softly" , "Moves silently and carefully" , "willies" , "Moves slowly - like servile people?" .)
