Insect let loose after another insect (6)
I believe the answer is:
beetle
'insect' is the definition.
(I know that beetle is a type of insect)
'let loose after another insect' is the wordplay.
'loose' indicates anagramming the letters (letters are loosened from their original positions).
'after' is a charade indicator (letters next to each other).
'another insect' becomes 'bee' (bee is a type of insect. I am not sure about the 'another' bit.).
'let' with letters rearranged gives 'tle'.
'tle' put after 'bee' is 'BEETLE'.
Can you help me to learn more?
(Other definitions for beetle that I've seen before include "8's (very small) friend" , "Insect with hardened forewings - scurry" , "Insect; dice game" , "Heavy wooden mallet for an insect" , "Insect with hard forewings" .)
