I may getaverbal beat down for this, but irregardless is notagrammatical error. Are you suggesting it is an error or just bad English? Irregardless, just thought someone should defend this poor word. Signed-

Usage Discussion of IRREGARDLESS
Irregardless originated in dialectal American speech in the early 20th century. Its fairly widespread use in speech called it to the attention of usage commentators as early as 1927. The most frequently repeated remark about it is that “there is no such word.” There is suchaword, however. It is still used primarily in speech, although it can be found from time to time in edited prose. Its reputation has not risen over the years, and it is stillalong way from general acceptance. Use regardless instead.
