Inexperienced about uranium, fail miserably after starting to outline a genus (9)

'outline a genus' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.

'inexperienced about uranium fail miserably after starting' is the wordplay.
I cannot really see how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is found in the answer.
'uranium' could be 'u' (U is the chemical symbol for uranium) and 'u' is found in the answer.
an anagram of 'fail' is 'lfia' which is present in the answer.
This may be the basis of clue (or it may be nonsense).

'to' acts as a link.

Can you help me to learn more?
