Phone sibling after years, clearing bad blood (8)
I believe the answer is:
dialysis
'phone sibling after years clearing bad blood' is the definition.
I can't tell whether this defines the answer.
'phone sibling after years' is the wordplay.
'phone' becomes 'dial' (dial phone is a kind of phone).
'sibling' becomes 'sis' (short for sister).
'after' says to put letters next to each other.
'years' becomes 'y' (abbreviation).
'sis' after 'y' is 'ysis'.
'dial'+'ysis'='DIALYSIS'
Can you help me to learn more?
(Other definitions for dialysis that I've seen before include "Procedure for one with kidney failure" , "Purification of the blood by causing it to flow through a membrane" , "Clinical purification of blood" , "It's used in the case of kidney failure" , "Kidney failure necessitates this procedure" .)
