The English language is funny, don't you think? It is so easy to make up your own words by adding -ish, -ing, -ly or whatever suffix you wish.
However, some people use the English language thinking they are correct, but missing the boat completely. Here are a few choice words/phrases/pronunciations:
"Supposebly"- This is used by the people who are just confused. However, the people who use this word are certain that their variation on this word is correct.
"Irregardless"- Though this is technically a word, it is misused and makes a person sound stupid.(Usage Note: Irregardless is a word that many mistakenly believe to be correct usage in formal style, when in fact it is used chiefly in nonstandard speech or casual 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.-Dictionary.com)
A lazy tongue: Pronouncing the word "Sale" as "Sell." Also pronouncing the word "Seal" as "Sell." For instance: "Did you see the sell they had at wet sell?" No joke, Andy and I heard this sentence actually spoken at Gateway mall. Yikes.
Dropping the 'T'- Usually found in Utah, this speech anomaly is also due to a lazy mouth. Words such as mountain and fountain mysteriously are rewritten as someone puts them into a sentence. "That fou_ain is right below the moun_ain...You know, just east of Lay_on?
"But at the same time"- I worked with a person who used this phrase countless times in one day (every day). Though she used it with confidence I very much doubt that she ever thought about the meaning of what she was saying. She would throw two thoughts at random into a sentence and link them with 'but at the same time'. "I like to drive to work, but at the same time, I could really go for a bologna sandwich."
Please feel free to add your own stories and examples. I'd love to hear them!
