Place having additional numbers around after I beg (7)
I believe the answer is:
implore
'beg' is the definition.
(synonyms)
'place having additional numbers around after i' is the wordplay.
I cannot quite understand how this works, but
'place' could be 'pl' (I've seen this in other clues) and 'pl' is found within the answer.
'additional' could be 'more' (synonyms) and 'more' is present in the leftover letters.
'i' is within the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
(Other definitions for implore that I've seen before include "Beg earnestly, plead" , "Beg earnestly, beseech" , "Ask earnestly" , "Beg earnestly, entreat" , "More lip (anag)" .)
