The remainder showed hesitation in disseminating tosh (6)
I believe the answer is:
others
'the remainder' is the definition.
(I've seen this in another clue)
'showed hesitation in disseminating tosh' is the wordplay.
I cannot quite understand how this works, but
'hesitation' could be 'er' (sound made while hesitating - um, er) and 'er' is located in the answer.
an anagram of 'tosh' is 'oths' which is within the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for others that I've seen before include "Certainly not us" , "People in throes - not us" , "He rots (anag.)" , "Not the same one already mentioned" , "Not the ones already mentioned" .)
