About the first in that place (5)
I believe the answer is:
there
'in that place' is the definition.
(over there)
'about the first' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'first' says to put letters next to each other.
're' put after 'the' is 'THERE'.
(Other definitions for there that I've seen before include "Thither" , "that particular place" , "On the spot" , "Exclamation of triumph or sympathy" , "please feel reassured!" .)
