Half buried part of a plant (3)
I believe the answer is:
bur
'a plant' 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?
'half buried' is the wordplay.
'half' indicates taking half.
'buried' with half the letters taken is 'BUR'.
'part of' acts as a link.
Can you help me to learn more?
(Other definitions for bur that I've seen before include "sticker" , "Seed-case" , "Prickly seed case" , "small drill" , "Clinging seed case" .)
