Judges predecessor a heavyweight (6)
I believe the answer is:
joshua
This might be a double definition.
'judges predecessor' is the first definition.
The definition suggests a singular noun which matches the answer.
'a heavyweight' is the second definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for joshua that I've seen before include "Moses' successor who conquered Jericho" , "Sir -- Reynolds, British painter" , "6th Old Testament book" , "Conqueror of Jericho" , "Fighter at Jericho" .)
