Replacements for broken spears (6)
I believe the answer is:
spares
'replacements' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'broken spears' is the wordplay.
'broken' is an anagram indicator.
'spears' anagrammed gives 'SPARES'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for spares that I've seen before include "Extras with spears" , "Replacement items, like tyres" , "Extras in case of necessity" , "Lets off; reserve parts" , "Is merciful towards, refrains from hurting" .)
