Where one parks one's butt? (7)
I believe the answer is:
ashtray
This could be a double definition.
'where one parks' is the first definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'one's butt?' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for ashtray that I've seen before include "Receptacle for tobacco detritus" , "Smoker's receptacle" , "Smoker's aid" , "Receptacle for tips" , "Place for cigarette ends" .)
