Analyse high praise that excludes yours truly (5)
I believe the answer is:
parse
'analyse' is the definition.
(I know that parse is a type of analyse)
'high praise that excludes yours truly' is the wordplay.
'high' is an anagram indicator (like drunk).
'that excludes' is a deletion indicator.
'yours truly' becomes 'I' (the person that set this crossword).
'praise' with 'i' taken away is 'prase'.
'prase' anagrammed gives 'PARSE'.
(Other definitions for parse that I've seen before include "Reaps (anag.)" , "Spear (anag.); analyse" , "Work out clue" , "Analyse syntactically" , "do grammatical analysis" .)
