On which there's a guiding hand at the plough? (6)
I believe the answer is:
tiller
'on which there's a guiding' is the definition.
I can't tell whether this defines the answer.
'hand at the plough?' is the wordplay.
'hand' becomes 'er' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'at' says to put letters next to each other (I've seen this in other clues).
'the plough?' becomes 'till' (I've seen this before).
'er' after 'till' is 'TILLER'.
Can you help me to learn more?
(Other definitions for tiller that I've seen before include "Steering gear - one who ploughs" , "steering contraption" , "Lever to turn the rudder on a boat" , "Boat's steering bar" , "Worker on the land found on board" .)
