Two things a lodger may be given with the piano (8)
I believe the answer is:
keyboard
'piano' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for keyboard that I've seen before include "one lays hands on" , "Part of piano. computer, etc" , "One produces notes" , "There are various characters on this" , "Computer essential" .)
