How important is it to use the 'recommended' edition of Chambers?
My copy is from 1999. (I can't justify buying every new release!) but in today's Azed 2,524 there's a word mine doesn't have -
— 7dn, Part in indecorous entertainment was unwonted.
All four crossing lights lead me to belief eve the answer is "usent", which isn't in my Chambers.
What edition do others use?
