Using coercion, get former partner to write regularly (6)
I believe the answer is:
extort
'using coercion get' is the definition.
I can't tell whether this definition defines the answer.
'former partner to write regularly' is the wordplay.
'former partner' becomes 'ex' (an ex-partner).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternating letters of 'write' are 'rt'.
'ex'+'to'+'rt'='EXTORT'
Can you help me to learn more?
(Other definitions for extort that I've seen before include "Obtain money by force or threat" , "Get by force" , "Take from by force or threat" , "Get through threatening" , "Extract money with menances" .)
