An endless labyrinth and one strong woman (6)
I believe the answer is:
amazon
'strong woman' is the definition.
(I've seen this before)
'an endless labyrinth and one' is the wordplay.
'an' becomes 'a'.
'endless' means to remove the last letter.
'labyrinth' becomes 'maze' (synonyms).
'and' says to put letters next to each other.
'one' becomes 'on' (I can't justify this - if you can you should believe this answer much more).
'maze' with its final letter removed is 'maz'.
'a'+'maz'+'on'='AMAZON'
Can you help me to learn more?
(Other definitions for amazon that I've seen before include "Strong, well-built woman" , "Female warrior - parrot - South American river" , "running through Peru, Colombia and Brazil" , "big river" , "S. America's longest river" .)
