Pretty little thing making a bed (4)
I believe the answer is:
bead
'pretty little thing' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'making a bed' is the wordplay.
'making' indicates an anagram.
'a'+'bed'='abed'
'abed' is an anagram of 'BEAD'.
Can you help me to learn more?
(Other definitions for bead that I've seen before include "A bit of the rosary" , "bit off necklace, say" , "Drop of liquid on a surface" , "Bauble" , "Part of a necklace" .)
