KrisKross would look around for an object of worship (4)
I believe the answer is:
idol
'an object of worship' is the definition.
(I've seen this before)
'kriskross would look around' is the wordplay.
'kriskross' becomes 'i' (I can't explain this - if you can you should believe this answer much more).
'would' becomes 'd' (I've seen this in other clues).
'look' becomes 'lo' (archaic term meaning 'look!').
'around' is a reversal indicator.
'lo' written backwards gives 'ol'.
'i'+'d'+'ol'='IDOL'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for idol that I've seen before include "False god" , "Worshipped figure (not painting); revered person" , "Effigy" , "Someone much loved" , "Graven image (sometimes false?)" .)
