Moving trapdoor has trapped husband like an insect (9)
I believe the answer is:
arthropod
'an insect' is the definition.
(thesaurus)
'moving trapdoor has trapped husband' is the wordplay.
I cannot really understand how this works, but
'husband' could be 'h' and 'h' is found within the answer.
an anagram of 'trapdoor' is 'artropod' which is within the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'like' is the link.
Can you help me to learn more?
(Other definitions for arthropod that I've seen before include "worker, perhaps" , "One has external skeleton" , "Such as a crustacean or spider" , "Invertebrate" , "Creature such as insect or crustacean" .)
