Shiny covering gutted Czech capital (6)
I believe the answer is:
chrome
'shiny covering' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'gutted czech capital' is the wordplay.
'gutted' says to hollow out the word (remove centre letters) (to gut something is to remove its insides).
'capital' becomes 'rome' (capital of Italy).
'czech' with its centre removed is 'ch'.
'ch'+'rome'='CHROME'
Can you help me to learn more?
(Other definitions for chrome that I've seen before include "Brilliant finish" , "Hard stuff for plating - yellow pigment" , "Shiny metal for plating" , "Deep yellow" , "Metallic element" .)
