Little one nailed low down? (3)
I believe the answer is:
toe
'low down?' is the 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?
'little one nailed' is the wordplay.
I cannot quite see how this works, but
'one' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
The remaining letters 'te' 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).
Can you help me to learn more?
(Other definitions for toe that I've seen before include "End of foot" , "One of the lower digits" , "Foot extremity." , "One with sock on" , "Pedal digit" .)
