They bring much woe to us chaps (5)
I believe the answer is:
women
'they' is the definition.
Both the definition and answer are plural nouns.
Maybe they are linked in a way I don't understand?
'much woe to us chaps' is the wordplay.
'much' means to remove the last letter (much but not all of the word).
'to us chaps' becomes 'men' (I can't explain this - if you can you should believe this answer much more).
'woe' with its final letter taken off is 'wo'.
'wo'+'men'='WOMEN'
'bring' acts as a link.
Can you help me to learn more?
(Other definitions for women that I've seen before include "Ladies" , "half of our race" , "Adult human females" .)
