School never cares about monitor safety (11)
I believe the answer is:
screensaver
'monitor safety' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'school never cares about' is the wordplay.
'school' becomes 'S'.
'about' is an anagram indicator.
'never'+'cares'='nevercares'
'nevercares' with letters rearranged gives 'creensaver'.
's'+'creensaver'='SCREENSAVER'
Can you help me to learn more?
(Other definitions for screensaver that I've seen before include "what slide show may be used for" , "Damage-reducing program for computer monitor" , "appearance of idle display" .)
