In what way a showpiece? (3)
I believe the answer is:
how
'in what way' is the definition.
(synonyms)
'a showpiece?' is the wordplay.
'HOW' is hidden in amongst the letters.
However, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for how that I've seen before include "Who (anag.)" , "See 16" , "By what means?" , "In what way?" , "In what manner or method?" .)
