Turn up on time at place (3)
I believe the answer is:
put
'place' is the definition.
(synonyms)
'turn up on time' is the wordplay.
'turn' says the letters should be written backwards.
'up on' becomes 'up' (similar in meaning).
'time' becomes 't' (abbreviation).
'up' back-to-front is 'pu'.
'pu'+'t'='PUT'
'at' is the link.
(Other definitions for put that I've seen before include "Place, lay" , "Set (in place)" , "Place in a location" , "Place; placed" , "Place in a position" .)
