Adverb
1. "without lack of regard" or "not without regard"

Adjective
1. "not disregardful"

While many claim it to be grammatically incorrect and brush it off as the dumb way of saying "regardless", there is a meaningful place for this word in the English language. The unreduced double negative formed by the prefix and affix acts as a redundant intensifier of the root word "regard"; meaning this word is useful in certain circumstances for emphasizing the sheer amount of regard or the mere presence of regard in a given situation. It is similar to the usage of superlative reflexive pronouns.
1. Irregardless of the anonymous tip, we decided to double the amount of guards.

2. The irregardless lifeguard noticed the drowning boy quickly.

3. I, myself, typed this irregardless of the lack of a sufficiently adequate definition.

Used by people who ignorantly mean to say regardless. According to webster, it is a word, but since the prefix "ir" and the suffx "less" both mean "not or with" they cancel each other out, so what you end up with is regard. When you use this to try to say you don't care about something, you end up saying that you do. Of course everyone knows what you mean to say and only a pompous,rude asshole will correct you.

A word used by uneducated people intending to sound intelligent. Often, the defendant will use this word in court in an attempt to impress the judge and jury. Educated people notice and those who use this word instantly identify themselves to educated people as being uneducated. Educated people rarely correct them because it helps educated people more easily identify them if they are well groomed.

Irregardless is an illegitimate word, you shitstains! Putting the prefix Ir before the word regardless effectively makes it a double negative; thus the meaning of the word becomes: "without without regard." so instead of the intended meaning, which is without regard, it becomes just the opposite: with regard to!
Irregardless is a non-word that many a tool mistakenly believe to be correct usage in formal style, when in fact it is used chiefly in nonstandard speech or uneducated writing. Coined in the United States in the early 20th century, it has met with a blizzard of condemnation for being an improper yoking of irrespective and regardless and for the logical absurdity of combining the negative ir- prefix and -less suffix in a single term. Although one might reasonably argue that it is no different from words with redundant affixes like debone and unravel, it has been considered a blunder for decades and will probably continue to be so.

An oft-word that is used regardless of its nonexistence—probably because of its perceived imaginary union between "irrespective" and "regardless."
It's not uncommon to see college students incorrectly use irregardless rather than regardless in their essays.
