Bathroom worker's turn to install tap that's left behind (6)
I believe the answer is:
relict
'left behind' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'bathroom worker's turn to install tap' is the wordplay.
'bathroom worker' becomes 'tiler' (I've seen this in another clue).
'turn' shows that the letters should be reversed in order.
'to install' indicates putting letters inside.
'tap' becomes 'C' (C for the cold tap).
'tiler' in reverse letter order is 'relit'.
'relit' placed around 'c' is 'RELICT'.
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for relict that I've seen before include "Remnant" , "Archaic word for widow" , "Widow - surviving group" , "Primitive survival; widow (arch.)" , "Old word for widow" .)
