They tend to rush over certain points (6)
I believe the answer is:
nurses
'they tend' is the definition.
The definition suggests an adverb but the answer is not.
'rush over certain points' is the wordplay.
'rush' becomes 'run'.
'over' says the letters should be written in reverse.
'certain points' becomes 'ses' (SE is an example. I am not sure about the 'certain' bit.).
'run' reversed gives 'nur'.
'nur'+'ses'='NURSES'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for nurses that I've seen before include "They take care of the sick" , "workers in colonies" , "Ministering angels" , "Cares for during illness" , "They tend the sick" .)
