Points shown by a nurse? (3)
I believe the answer is:
sen
'a nurse?' is the definition.
(abbreviation for Senior Enrolled Nurse)
'points shown by' is the wordplay.
'points' becomes 'se' (two compass points).
'shown' becomes 'n' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'by' says to put letters next to each other.
'se'+'n'='SEN'
Can you help me to learn more?
(Other definitions for sen that I've seen before include "Japanese money unit" , "Fraction of yen" , "Very small change for Japanese" , "nurse" , "ready for Japan" .)
