Bishop replaces first part of name given to tower (5)
I believe the answer is:
babel
'to tower' is the definition.
(I've seen this before)
'bishop replaces first part of name' is the wordplay.
I cannot quite understand how this works, but
'bishop' could be 'b' (chess abbreviation) and 'b' is present in the answer.
'first' could be 'a' (first letter of the alphabet) and 'a' is located in the answer.
'name' could be 'bel' and 'bel' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'given' acts as a link.
Can you help me to learn more?
(Other definitions for babel that I've seen before include "Confusion of noise" , "Biblical tower location" , "All talking at once" , "Confused din of voices" , "Biblical city with a tower" .)
