With current lines, Shakespeare showing Iago's motivation? (3,4)
I believe the answer is:
ill will
'iago's motivation?' is the definition.
I can't tell whether this defines the answer.
'with current lines shakespeare' is the wordplay.
'with' says to put letters next to each other.
'current' becomes 'I' (symbol for electric current).
'lines' becomes 'll' (l is an abbreviation for line).
'shakespeare' becomes 'will' (I've seen this in another clue).
'i' put next to 'll' is 'ill'.
'ill'+'will'='ILL-WILL'
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for ill will that I've seen before include "Hostility, unkind feeling" , "Disposition of enemy" , "Rancour" , "causing resentment" , "Bad feeling towards, hostility" .)
