Spell words wrong here, with typos (3,6)
I believe the answer is:
hey presto
'spell words' is the definition.
(I've seen this before)
'wrong here with typos' is the wordplay.
'wrong' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'here' after 'typos' is 'typoshere'.
'typoshere' with letters rearranged gives 'HEY-PRESTO'.
(Other definitions for hey presto that I've seen before include "Conjuror's exclamation at the climax of a trick" , "revealing remark?" , "Spell words" , "Conjurer's exclamation" , "suddenly, as if by magic" .)
