Daughter and mum given radium injection in theatre (5)
I believe the answer is:
drama
'in theatre' is the definition.
(I know that drama is part of theatre)
'daughter and mum given radium injection' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'and' is a charade indicator (letters next to each other).
'mum' becomes 'ma' (ma can mean mother).
'given radium' becomes 'ra' (Ra is the chemical symbol for radium. I am not sure about the 'given' bit.).
'injection' is an insertion indicator.
'd'+'ma'='dma'
'dma' going around 'ra' is 'DRAMA'.
Can you help me to learn more?
(Other definitions for drama that I've seen before include "Literary genre for the stage" , "theatre performance" , "Stage production" , "Theatrical production" , "Play - crisis" .)
