Put a tag on Ivan's back or find someone who can read maps! (9)
I believe the answer is:
navigator
'someone who can read maps' 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?
'put a tag on ivan's back or' is the wordplay.
'put a tag' becomes 'gat' (I am not sure about this - if you are sure you should believe this answer much more).
'on' says to put letters next to each other.
'back' says the letters should be written in reverse.
'ivan' in reverse letter order is 'navi'.
'gat' put after 'navi' is 'navigat'.
'navigat'+'or'='NAVIGATOR'
'find' acts as a link.
Can you help me to learn more?
(Other definitions for navigator that I've seen before include "Assistant to driver" , "One directs the course, of a ship say" , "course director" , "crew member" , "Prince Henry, say" .)
