Is there a word or term for a person who is proudly ignorant? A person who differentiates "Your & You're" and chooses to be grammatically incorrect [duplicate]

Solution 1:

Also consider:
• opinionated, “Having very strong opinions” and, in the form self-opinionated, “Holding to one's own opinion obstinately, stubbornly and unreasonably”
• loudmouth or blowhard, “One who talks too much or too loudly, especially in a boastful or self-important manner”
• obnoxious (unpleasant, offensive, annoying, odious)
• eristic, “One who makes specious arguments; one who is is disputatious”
• bigoted, “having or revealing an obstinate belief in the superiority of one’s own opinions and a prejudiced intolerance of the opinions of others”
• egotist, “A person who believes in his own importance or superiority”
• bumptious, “Obtrusively pushy; self-assertive to a pretentious extreme”
• self important, “Having, or behaving as if having, too high an opinion of one's own importance”
• solipsist, “One who adheres to self-absorption and an ignorance of the views or needs of others”
• smart aleck or smart ass, “One who is pretentious about their own cleverness or knowledge; a know-it-all”
• wiseacre, “One who feigns knowledge or cleverness; an insolent upstart”; also “(obsolete) A learned or wise man”

Three of the above appear in Is there a word for a person who doesn't think the rules apply to him?. Also see:

• "Arrogant" vs. "conceited"
• A polite substitution for "lamer"
• Someone who forms their own opinion
• Ignorantly dishonest
• Is there a word to describe someone who tends to disagree with others only to upset them?.

Solution 2:

An ignoranus is somebody who manages to be both ignorant and an asshole.

Alas it is not a real word, but just a play on ignoramus. I first came across it in an email listing the winners of the "The Washington Post's Mensa invitational", a contest which invites readers to take "any word from the dictionary, alter it by adding, subtracting, or changing one letter, and supply a new definition."

Unfortunately, the contest seems to have been fictitious but the list was so good that it has now taken on a life of its own (and is really worth a read). In any case, ignoranus is gaining quite a following as can be seen by the ~66,100 google hits for the word. I believe it to be a great addition to the language and it would fit your intended use pretty well; let's promote it! I would refer to the person you describe as an arrogant ignoranus.

Solution 3:

'Conceited' might be the word you are looking for. These days it tends to mean having an overly favourable opinion of oneself.

Also consider 'cocky', 'smug', 'complacent' and 'vain'.

Solution 4:

I don't know if there's an equivalent one word answer but I think the phrase "know-nothing know-it-all" is bang on.
