Frilly thing that is something worn in bed? (7)
I believe the answer is:
nightie
'worn in bed?' is the 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?
'frilly thing that is something' is the wordplay.
I cannot really see how this works, but
an anagram of 'thing' is 'night' which is within the answer.
'that is' could be 'ie' (short for Latin 'id est', 'that is') and 'ie' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for nightie that I've seen before include "Sleepwear" , "Late shift perhaps" , "covering for retired person" , "Lingerie item" , "cover for retiring" .)
