Fools? The ordinary people will ignore them (5)
I believe the answer is:
asses
'fools?' is the definition.
(ass is a kind of fool)
'the ordinary people will ignore them' is the wordplay.
'ordinary people' becomes 'masses' (I've seen this in another clue).
'will ignore' indicates named letters should be taken away.
'the'+'masses'='themasses'
'themasses' with 'them' taken away is 'ASSES'.
(Other definitions for asses that I've seen before include "More than one fool" , "Fools, quadrupeds" , "Dolts" , "dim bulbs?" , "Idiots" .)
