Asian dictator hiding yen in part of Ireland (4)
I believe the answer is:
mayo
'part of ireland' is the definition.
(I've seen this before)
'asian dictator hiding yen' is the wordplay.
'asian dictator' becomes 'mao' (Chinese dictator Chairman Mao. I am not sure about the 'asian' bit.).
'hiding' indicates putting letters inside.
'yen' becomes 'y' (resembles the symbol for the currency of Japan).
'mao' placed around 'y' is 'MAYO'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for mayo that I've seen before include "Irish county (county town, Castlebar)" , "Irish county; dressing" , "County of Western Eire" , "radio presenter" , "Cold, creamy sauce (abbr)" .)
