One used in dressing a window? (4)
I believe the answer is:
sash
This clue might be a double definition.
'one used in dressing' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'a window?' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for sash that I've seen before include "Girdle" , "Style of window" , "Decorative belt" , "Decoration for the twelfth" , "Sliding window frame" .)
