Nurse and husband needing shady garden seat (7)
I believe the answer is:
harbour
'nurse' is the definition.
(I know that nurse can be written as harbour)
'husband needing shady garden seat' is the wordplay.
'husband' becomes 'h'.
'needing' says to put letters next to each other.
'shady garden seat' becomes 'arbour' (an arbour is a shaded area of a garden).
'h'+'arbour'='HARBOUR'
'and' is the link.
(Other definitions for harbour that I've seen before include "Place of refuge" , "Hide - entertain - port" , "Tie up the shipping here" , "Keep in mind; refuge" , "Sheltered port" .)
