One can see through this note penned by bereaved woman (6)
I believe the answer is:
window
'one can' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'through this note penned by bereaved woman' is the wordplay.
'through' becomes 'in'.
'this note' becomes 'd' (musical note).
'penned by' indicates putting letters inside (inserted letters are penned in).
'bereaved woman' becomes 'wow' (I can't explain this - if you can you should believe this answer much more).
'in'+'d'='ind'
'ind' inserted within 'wow' is 'WINDOW'.
'see' acts as a link.
Can you help me to learn more?
(Other definitions for window that I've seen before include "Skylight" , "Transparent panel of glass" , "Opening (of opportunity?)" , "Glass-filled opening" , "Glassy area" .)
