'a regular course of action' is the definition.
I can't tell whether this definition defines the answer.

'rake round container' is the wordplay.
'rake' becomes 'roue' (both can mean an immoral man).
'round' indicates putting letters inside.
'container' becomes 'tin' (tin is a kind of container).
'roue' placed around 'tin' is 'ROUTINE'.

Can you help me to learn more?

(Other definitions for routine that I've seen before include "Regular procedure" , "boring" , "Customary" , "Regular sequence of actions" , "Fixed sequence of actions" .)
