Inquisitor 1321

[Ripper]

I'm really struggling with this one!
Please could someone 'kick start' me on a couple to get me going again.
7 across: Leave religious king lost in Baku (5) no letters I'm afraid, but the corrected letter should be O
33 down: I start to keep 150 cows for MacDonald (4) _AKY
sorry, can I have help with another:
20 across: Mists absent near ground (6) _ _ R _N_ I keep thinking arena, but it's the wrong length & wrong!!
Thanks in advance

Ripper, 7A is Azerbaijan currency. The other two clues have shorter answers than provided in the grid

Thank you Gregsdad
I fear this one may defeat me! - but I'll keep going.

You have the right answer to 20a.
The wordplay is A= absent, near 'ground' (anagramised) = RENA.
Misprint in definition is Lists = arena.
Remember, the initial grid entry doesn't have to fill all the cells.
Leave the first cell empty.

. . and 33d is a two-letter Scottish word for cattle.

Thank you boreas, I'll put my little grey cells to work!
