Get a raise, being within the fold? (8)
I believe the answer is:
increase
'get a raise' is the definition.
I can't judge whether this definition defines the answer.
'within the fold?' is the wordplay.
'within' becomes 'in'.
'the fold?' becomes 'crease' ('crease' can be a synonym of 'fold').
'in'+'crease'='INCREASE'
'being' is the link.
Can you help me to learn more?
(Other definitions for increase that I've seen before include "Grow greater" , "Augment or enlarge (8)." , "step up" , "Grow, add to" , "Become greater in number" .)
