Analyze closely (5)
I believe the answer is:
parse
'analyze closely' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for parse that I've seen before include "Resolve (a sentence) into its constituent parts" , "Work out clue" , "Deconstruct grammatically" , "Spear (anag.); analyse" , "analyse this, for instance" .)
