Ugandan dictator's name held in disdain regularly (3)
I believe the answer is:
idi
'ugandan dictator's name held' is the definition.
I know nothing about this answer so I can't tell whether this works.
'disdain regularly' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'disdain' are 'IDI'.
'in' is the link.
Can you help me to learn more?
(Other definitions for idi that I've seen before include "Former dictator of Uganda, ... Amin" , "First name of Ugandan dictator, 1971-79" .)
