Apologies Tony, I've misled you inadvertently (caused largely by working from a doc not containing clue numbers as am in remote Scottish wilderness!).
5dn clashes with 17ac. 5dn is entered as is and def is abbreviated noun for activity representing acting for pleasure.
11ac clashes with 4dn. 4dn is entered as is and def is noun for fostering environment.
If you need a further push just ask. Sorry again for earlier slip-up.
