22A A Boundary Round Enemy Alliance

[Aeolus]

A?I?.
If this is supposed to be AXIS, where's the logic?

[Jackdaw33]

Round is one of the ways setters use to indicate that the word should be reversed.

[Aeolus]

OK, thank you fellow night owls. Didn't connect boundary with cricket.

[Jackdaw33]

...it can also mean to surround another word or indicate the letter O. Such are the delights of cryptic crosswords.

[Aeolus]

OKAY, OKAY Jackdaw, I know the (lack of) logic used by modern setters, just not on the right wavelength! Nighty nights.
