One trap set during harangue in Spring (9)
I believe the answer is:
originate
'in spring' is the definition.
(I've seen this before)
'one trap set during harangue' is the wordplay.
'one' becomes 'I' (Roman numeral).
'trap set' becomes 'gin' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'during' means one lot of letters goes inside another.
'harangue' becomes 'orate' (I've seen this before).
'i'+'gin'='igin'
'igin' going inside 'orate' is 'ORIGINATE'.
Can you help me to learn more?
(Other definitions for originate that I've seen before include "Stem" , "Create; begin" , "Create, initiate" , "pioneer" , "From kick off" .)
