Right after His Excellency, start to eat at this place (4)
I believe the answer is:
here
'at this place' is the definition.
(synonyms)
'right after his excellency start to eat' is the wordplay.
'right' becomes 'r' (common abbreviation).
'after' means one lot of letters go next to another.
'his excellency' becomes 'he'.
'start to' indicates taking the first letters.
The first letter of 'eat' is 'e'.
'r' put after 'he' is 'her'.
'her'+'e'='HERE'
(Other definitions for here that I've seen before include "Present - at this point" , "At this stage" , ""___ be dragons" (old map inscription?)" , "The present location" , "In this place - present" .)
