Character in sailor suit having abandoned land, do nothing about it (6,4)
I believe the answer is:
donald duck
'character in sailor suit' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'abandoned land do nothing about it' is the wordplay.
'abandoned' indicates anagramming the letters (the original order is abandoned).
'nothing' becomes 'duck' (duck means zero in cricket).
'about it' is an insertion indicator (some letters go around or about others).
'land'+'do'='landdo'
'landdo' is an anagram of 'onaldd'.
'onaldd' inserted into 'duck' is 'DONALD DUCK'.
'having' acts as a link.
Can you help me to learn more?
(Other definitions for donald duck that I've seen before include "bird apparently brought to life" , "Screen favourite" , "Walt Disney character" , "Bradman getting no runs" , "Disney cartoon character" .)
