I ring haphazardly round first, as a beginning (6)
I believe the answer is:
origin
'a beginning' is the definition.
(I know that origin is a type of beginning)
'i ring haphazardly round first' is the wordplay.
'haphazardly' indicates an anagram.
'round' becomes 'o' (round can mean a round object).
'first' is a charade indicator (letters next to each other).
'i'+'ring'='iring'
'iring' is an anagram of 'rigin'.
'rigin' after 'o' is 'ORIGIN'.
'as' is the link.
(Other definitions for origin that I've seen before include "Square one" , "Source - provenance" , "Where X meets Y" , "Beginning, starting point" , "First thing" .)
