Followed for being pure, say (6)
I believe the answer is:
chased
'followed' is the definition.
(to chase someone is to follow them)
'pure say' is the wordplay.
'pure' becomes 'chaste' (chaste means abstaining from sex).
'say' shows a homophone (sound like).
'chaste' sounds like 'CHASED'.
'for being' is the link.
(Other definitions for chased that I've seen before include "Engraved; rushed" , "Decorated metal with engraved or embossed work" , "Wooed" , "Pursued at speed" , "Pursued, ran after" .)
