Standard kanji form for 'irregularity' or 'asymmetry'. 斉 means 'equal' or 'uniform'.
Alternate kanji form. 整 means 'order' or 'arrangement', emphasizing lack of order rather than lack of equality.
Compound of 不 (fu, 'not') and 斉 (sei, 'equal' or 'uniform'). The spelling 不整 uses 整 (sei, 'order') instead, with a similar meaning. The exact historical derivation is uncertain, but the word follows a common Sino-Japanese pattern of negation.
