Prince and I clean about blooming irregularity (7)

I believe the answer is:

panicle

I'm a little stuck... Click here to teach me more about this clue!

'blooming irregularity' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.

'prince and i clean about' is the wordplay.
'prince' becomes 'p' ().
'and' means one lot of letters go next to another.
'about' indicates anagramming the letters.
'i'+'clean'='iclean'
'iclean' with letters rearranged gives 'anicle'.
'p'+'anicle'='PANICLE'

Can you help me to learn more?
