What monarchs do in inclement weather, we’re told (5)
I believe the answer is:
reign
'what monarchs do' is the definition.
The definition suggests a singular noun which matches the answer.
'inclement weather we're told' is the wordplay.
'inclement weather' becomes 'rain'.
'we're told' indicates a 'sounds like' (homophone) clue.
'rain' sounds like 'REIGN'.
'in' is the link.
Can you help me to learn more?
(Other definitions for reign that I've seen before include "Spell in office" , "Hold sway, rule" , "Monarch's period" , "time in power" , "are unbeatable!" .)
