Where one may sit or get to one's feet (5)
I believe the answer is:
stand
'get to one's feet' is the definition.
(I've seen this before)
'where one may sit' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is located in the answer.
The remaining letters 'std' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'or' acts as a link.
Can you help me to learn more?
(Other definitions for stand that I've seen before include "Raised platform; tolerate" , "Remain unaltered, tolerate" , "Be upright; attitude" , "Get to one's feet" , "station" .)
