Old females pursuing Rod cease paying any attention (6,3)
I believe the answer is:
switch off
'old females pursuing rod cease paying any attention' is the definition.
I can't judge whether this defines the answer.
'old females pursuing rod' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'females' becomes 'ff' (the abbreviation for female repeated).
'pursuing' is a charade indicator (letters next to each other).
'rod' becomes 'switch' (I've seen this before).
'o'+'ff'='off'
'off' after 'switch' is 'SWITCH OFF'.
Can you help me to learn more?
(Other definitions for switch off that I've seen before include "Lose concentration" , "Disconnect power" , "Stop paying attention" .)
