Monster? Bit of a titchy dragon (5)
I believe the answer is:
hydra
'monster?' is the definition.
(Hydra is an example)
'bit of a titchy dragon' is the wordplay.
'bit of' says the answer is hidden in the clue.
'HYDRA' is hidden in the letters of 'titchy dragon'.
(Other definitions for hydra that I've seen before include "Nine-headed monster killed by Hercules" , "Multi-headed monster killed by Hercules" , "that regenerated after cuts at the top" , "Mythical nine-headed monster" , "Stars" .)
