Comments on the clue

1.	Difficult to solve this one as the definition doesn't immediately leap out at the solver
2.	No clear anagram indicator, and not sure where this definition has come from. Surface reading is pretty meaningless too.
3.	Don't like the two "a"s and I don't understand the definition at all. The surface is also a tad forced.
4.	The definition is inadequate, and the indefinite articles in the wordplay should not have been there.
