The skipper and I plot movement (5)
I believe the answer is:
pilot
'the skipper' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'i plot movement' is the wordplay.
'movement' is an anagram indicator (letters move around).
'i'+'plot'='iplot'
'iplot' anagrammed gives 'PILOT'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for pilot that I've seen before include "Guide - flier" , "air traffic controller?" , "This person can be found in a plane or a boat" , "Aircraft captain" , "Guide, steer" .)
