Lost nursing home initially remains here? (7)
I believe the answer is:
ashtray
'remains here?' is the definition.
(dish for cigarette remains)
'lost nursing home initially' is the wordplay.
'lost' becomes 'astray' (synonyms).
'nursing' means one lot of letters goes inside another.
'initially' suggests taking the first letters.
The first letter of 'home' is 'h'.
'astray' enclosing 'h' is 'ASHTRAY'.
(Other definitions for ashtray that I've seen before include "Where to rest cigarette" , "where smoking remains are found" , "Place for cigarette ends" , "Dish for smokers" , "Place for detritus from cigarettes, cigars etc" .)
