Something ____ upon is begun (7)

I believe the answer is:

entered

(Other definitions for entered that I've seen before include "moved in" , "Enrolled or went in" , "Logged; arrived" , "Went in and registered as competitor" , "Came in; recorded" .)

I've seen this clue in The Sunday Times and The Times.
