Pole back in Katowice travelled on (4)
I believe the answer is:
rode
'travelled on' is the definition.
'rode' can be an answer for 'travelled' (eg travelled on a horse). I'm not certain of the 'on' bit.
'pole back in katowice' is the wordplay.
'pole' becomes 'rod' (synonyms).
'back in' says to take the final letters (the 'back' of the word).
The final letter of 'katowice' is 'e'.
'rod'+'e'='RODE'
Can you help me to learn more?
(Other definitions for rode that I've seen before include "Cycled" , "Went by horse" , "Travelled on the back of an animal" , "Came by bike" , "Travelled by bike" .)
