More soldiers and frontiersmen violently besieging church (14)
I believe the answer is:
reinforcements
'more soldiers' is the definition.
Although both the answer and definition are plural nouns, I can't understand how they can define each other.
'frontiersmen violently besieging church' is the wordplay.
'violently' is an anagram indicator (letters are violently disrupted).
'besieging' means one lot of letters goes inside another.
'church' becomes 'CE' (Church of England).
'frontiersmen' anagrammed gives 'reinforments'.
'reinforments' placed around 'ce' is 'REINFORCEMENTS'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for reinforcements that I've seen before include "Back-up troops" , "Backups" , "Extra troops" .)
