Score absent from bottom of table (6)
I believe the answer is:
notate
'score' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for notate that I've seen before include "Record, say" , "Write down, music or dance steps say" , "Put down in symbols" , "Set down (in symbols)" , "Use symbols to record (eg, music)" .)
