Son using which method to lead trial presentation? (8)
I believe the answer is:
showcase
'son using which method' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'to lead trial presentation?' is the wordplay.
'to lead' is a charade indicator (letters next to each other).
'trial' becomes 'case' (I've seen this in other clues).
'presentation?' becomes 'show' (presentation is a kind of show).
'case' after 'show' is 'SHOWCASE'.
Can you help me to learn more?
(Other definitions for showcase that I've seen before include "Museum display unit" , "exhibition place" , "Play" , "Exhibit, display" , "to suit trophy-holder" .)
