North toured by first person from Berlin -- not very far (4)
I believe the answer is:
inch
'not very far' is the definition.
(I've seen this before)
'north toured by first person from berlin' is the wordplay.
'north' becomes 'N' (abbreviation).
'toured by' indicates putting letters inside (tour can mean to go around).
'first person' becomes 'I' (first-person pronoun).
'from berlin' becomes 'ch' (I am not sure about this - if you are sure you should believe this answer much more).
'i'+'ch'='ich'
'n' put within 'ich' is 'INCH'.
Can you help me to learn more?
(Other definitions for inch that I've seen before include "Edge towards" , "Short length" , "The island is very small in length" , "Edge slowly" , "Small measurement unit of distance" .)
