Misguidedly attach empty wheelchair to the bottom of S&M gadget (10)
I believe the answer is:
smartwatch
'sm gadget' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'misguidedly attach empty wheelchair to the bottom' is the wordplay.
'misguidedly' is an anagram indicator.
'empty' means to remove the middle letters.
'to' says to put letters next to each other (I've seen this in other clues).
'the bottom' becomes 'sm' (I can't explain this - if you can you should believe this answer much more).
'wheelchair' with its middle removed is 'wr'.
'attach'+'wr'='attachwr'
'attachwr' anagrammed gives 'artwatch'.
'artwatch' after 'sm' is 'SMARTWATCH'.
'of' acts as a link.
Can you help me to learn more?
