Rustic ploughing frame is gripped by left hand (8)
I believe the answer is:
yokelish
'rustic' is the definition.
(I've seen this before)
'frame is gripped by left hand' is the wordplay.
'frame' becomes 'yoke' (I've seen this before).
'gripped by' is an insertion indicator.
'left hand' becomes 'lh' (this could be a standard abbreviation of which I'm unaware).
'is' put into 'lh' is 'lish'.
'yoke'+'lish'='YOKELISH'
'ploughing' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Another definition for yokelish that I've seen is " Rustic".)
