Wave around old Kalashnikov, ultimately bringing about surrender (4,4)
I believe the answer is:
roll over
'about surrender' is the definition.
Although both the answer and definition are verbs in their base form, I don't understand how one could define the other.
'wave around old kalashnikov ultimately' is the wordplay.
'wave' becomes 'roller' (roller is a kind of wave).
'around' is an insertion indicator.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'ultimately' indicates one should take the final letters.
The last letter of 'kalashnikov' is 'v'.
'o'+'v'='ov'
'roller' placed around 'ov' is 'ROLL-OVER'.
'bringing' is the link.
Can you help me to learn more?
(Other definitions for roll over that I've seen before include "Turn in bed from one side to the other" , "Turn turtle (as a jackpot might do?)" .)
