Ancient Cretan in love going among us (6)
I believe the answer is:
minoan
'ancient cretan' is the definition.
(as in the Minoan civilisation of Crete)
'in love going among us' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'going among' indicates putting letters inside.
'us' becomes 'man' (mankind).
'in'+'o'='ino'
'ino' inserted inside 'man' is 'MINOAN'.
(Other definitions for minoan that I've seen before include "Bronze Age civilisation" , "of an earlier civilisation" , "of people in the Bronze Age" , "Of an ancient Cretan civilisation" , "Someone in Bronze Age Crete" .)
