Turn off before river to get help (7)
I believe the answer is:
nurture
'help' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'turn off before river' is the wordplay.
'off' is an anagram indicator.
'before' means one lot of letters go next to another.
'river' becomes 'ure' (river in Yorkshire).
'turn' with letters rearranged gives 'nurt'.
'nurt'+'ure'='NURTURE'
'to get' is the link.
Can you help me to learn more?
(Other definitions for nurture that I've seen before include "Care for and protect" , "Raise" , "Cultivate" , "Rue runt involved in process of rearing" , "Rear (a child); cherish" .)
