Three ran that way (5)
I believe the answer is:
there
'that way' is the definition.
(I've seen this in another clue)
'three ran' is the wordplay.
'ran' indicates an anagram (letters have run around).
'three' is an anagram of 'THERE'.
(Other definitions for there that I've seen before include "Place: as indicated" , "it may be said to be comforting" , "Word of comfort" , "In that respect" , "Ether (anag)" .)
