Good person getting out of bed coming in to help (7)
I believe the answer is:
support
'to help' is the definition.
(support is a kind of help)
'good person getting out of bed coming' is the wordplay.
'good person' becomes 'st' (saint).
'getting' indicates putting letters inside.
'out of bed' becomes 'up' (synonyms).
'coming' becomes 'por' (I am not sure about this - if you are sure you should believe this answer much more).
'up'+'por'='uppor'
'st' enclosing 'uppor' is 'SUPPORT'.
'in' is the link.
Can you help me to learn more?
(Other definitions for support that I've seen before include "base" , "Bear; assistance" , "Bolster or back up" , "Bear the weight of (something)" , "Give assistance to" .)
