There are several other words: attempt, company, concern, courage, crusade, project and pursuit that fit the clue, but I feel VENTURE is the closest to the letters you submitted.
Hi Dutchy, Thank you for your help with this one, l looked again at 61a straying and changed it to ERRANT, then the T fitted into the clue very well, that meant that of course you are right VENTURE, once again THAnk You. :->
