Generally accepted cult's spineless creatures (7)
I believe the answer is:
insects
'spineless creatures' is the definition.
'insects' can be an answer for 'creatures' (insect is a kind of creature). I'm not certain of the 'spineless' bit.
'generally accepted cult's' is the wordplay.
'generally accepted' becomes 'in' (I've seen this in other clues. I am not sure about the 'generally' bit.).
'cult's' becomes 'sect's' (religious sect).
'in'+'sects'='INSECTS'
Can you help me to learn more?
(Other definitions for insects that I've seen before include "Small animals" , "Small invertebrate creatures" , "Bees, flies, etc." , "crawlers, perhaps" , "Bugs" .)
