Misguided step, just a nuisance (4)
I believe the answer is:
pest
'nuisance' is the definition.
(I've seen this before)
'misguided step' is the wordplay.
'misguided' indicates anagramming the letters (I've seen this in other clues).
'step' is an anagram of 'PEST'.
'just a' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for pest that I've seen before include "Annoying person" , "Aphis" , "Annoying nuisance" , "Plague" , "Destructive creature" .)
