Simple farmer one used to steer (6)
I believe the answer is:
tiller
This might be a double definition.
'simple farmer' is the first definition.
'tiller' can be an answer for 'farmer' (I've seen this before). I'm not certain of the 'simple' bit.
'one used to steer' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for tiller that I've seen before include "Farmer" , "Handle for turning rudder" , "Bar used to turn rudder in small boat" , "Steering device -- ploughman" , "Rudder's steering handle" .)
