Rang at once and praised (8)
I believe the answer is:
extolled
'praised' is the definition.
(extolling is a kind of praising)
'rang at once' is the wordplay.
'rang' becomes 'tolled' (tolling is a kind of ringing).
'at' says to put letters next to each other (I've seen this in other clues).
'once' becomes 'ex'.
'tolled' put after 'ex' is 'EXTOLLED'.
'and' is the link.
(Other definitions for extolled that I've seen before include "Praised and glorified" , "magnified" , "Acclaimed" , "cracked up" , "Praised highly, lauded" .)
