Bad time for a tiny tot (4)
I believe the answer is:
mite
'a tiny tot' is the definition.
'mite' can be an answer for 'tot' (thesaurus). I'm not sure about the 'a tiny' bit.
'bad time' is the wordplay.
'bad' indicates anagramming the letters.
'time' with letters rearranged gives 'MITE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for mite that I've seen before include "Microscopic animal" , "The Biblical widow's offering" , "Microscopic creature" , "Tiny contribution, child" , "Child; a small amount" .)
