One insect let loose after another (6)
I believe the answer is:
beetle
'another' is the definition.
Both the definition and answer are adjectives. Maybe you can see an association between them that I can't see?
'one insect let loose after' is the wordplay.
'one insect' becomes 'bee' (bee is a kind of insect).
'loose' indicates an anagram (letters are loosened from their original positions).
'after' says to put letters next to each other.
'let' anagrammed gives 'tle'.
'bee'+'tle'='BEETLE'
Can you help me to learn more?
(Other definitions for beetle that I've seen before include "Scurry - iconic small car" , "Beater" , "Iconic German car, first produced in 1938" , "Type of insect" , "E.g. ladybird" .)
