Keeps dates in order (7)
I believe the answer is:
detains
'keeps' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
'dates in order' is the wordplay.
'order' is an anagram indicator.
'dates'+'in'='datesin'
'datesin' with letters rearranged gives 'DETAINS'.
Can you help me to learn more?
(Other definitions for detains that I've seen before include "Delays" , "Stops" , "Holds back" .)
