Land first of delayed aeroplanes in fine weather (5)
I believe the answer is:
sudan
'land' is the definition.
(Sudan is an example)
'first of delayed aeroplanes in fine weather' is the wordplay.
'first of' says to take the initial letters.
'in' is an insertion indicator.
'fine weather' becomes 'sun' (I have seen 'Nice weather' mean 'sun' so perhaps 'weather' could also mean 'sun'. I am not sure about the 'fine' bit.).
The first letters of 'delayed aeroplanes' is 'da'.
'da' put inside 'sun' is 'SUDAN'.
Can you help me to learn more?
(Other definitions for sudan that I've seen before include "Country in NE Africa, capital Khartoum" , "African nation" , "Country in NC Africa, capital Khartoum" , "Country between Egypt and Zaire" , "African country on the Red Sea" .)
