Note that may be read both ways (5)
I believe the answer is:
minim
This could be a double definition.
'note that may be' is the first definition.
'minim' can be an answer for 'note' (type of musical note). I am not sure about the remainder of the definition.
'both ways' is the second definition.
'read' acts as a link.
Can you help me to learn more?
(Other definitions for minim that I've seen before include "Quarter of a breve" , "A note in music, half as long as a semi-breve- it's a palindrome" , "Half-semibreve" , "Note with value of half a semibreve" , "Musical note - small amount of liquid" .)
