The leg that is held up in the picture (5)
I believe the answer is:
image
This could be a double definition.
'the leg that is held up' 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?
'the picture' is the second definition.
(synonyms)
'in' acts as a link.
Can you help me to learn more?
(Other definitions for image that I've seen before include "Likeness; statue" , "Likeness; metaphor" , "Iconic representation" , "Figure (of speech?)" , "Visual or mental representation" .)
