Irishman, one who loves his country, eschews riot (3)
I believe the answer is:
pat
'irishman' is the definition.
(Patrick is a common Irish name)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for pat that I've seen before include "Knob (of butter)" , "Touch lightly - bit of butter?" , "Touch gently; glib" , "Small butter piece" , "Girl" .)
