Keeps dates in order (7)

Ross

I believe the answer is:

detains

I'm a little stuck... Click here to teach me more about this clue!

'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" .)
