Ties cleverly in position (4)
I believe the answer is:
site
'position' is the definition.
(both can mean a location or setting)
'ties cleverly' is the wordplay.
'cleverly' is an anagram indicator (a clever or tricky version of the letters).
'ties' is an anagram of 'SITE'.
'in' acts as a link.
(Other definitions for site that I've seen before include "station" , "setting" , "Building plot" , "Web location; place" , "Area set aside for building" .)
