From YourDictionary.com, which, unfortunately, is not my dictionary. I prefer Dictionary.com.
NO: affidavid YES: affidavit Even if your lawyer's name is ''David,'' he issues affidavits.
NO: athelete, atheletic YES: athlete, athletic Two syllables are enough for "athlete."
NO: bob wire YES: barbed wire No, this word wasn't named for anyone named ''Bob;'' it should be "barbed wire," although the suffix -ed, meaning ''having,'' is fading away in the U.S.
NO: Calvary YES: cavalry It isn't clear why we say, ''Mind your Ps and Qs'' when we have more difficulty keeping up with our Ls and Rs. Had there been a cavalry in Jesus' time, perhaps Calvary would not have been so tragic.
NO: card shark YES: cardsharp Cardsharps probably won't eat you alive, though they are adept at cutting your purse strings.
NO: chester drawers YES: chest of drawers The drawers of Chester is a typical way of looking at these chests down South but it misses the point.
NO: drownd YES: drown You add the [d] only to the past tense and past participle.
NO: expresso YES: espresso While I can't express my love for espresso enough, this word was borrowed from Italian well after the Latin prefix ex- had developed into es-.
NO: forte YES: fort The word is spelled "forte" but the [e] is pronounced only when speaking of music, as a "forte passage." The words for a strong point and a stronghold are pronounced the same: [fort].
NO: Heineken remover YES: Heimlich maneuver This term is mispronounced many different ways. This is just the funniest one we have heard. This maneuver (manoeuvre) was named for US surgeon Henry Jay Heimlich. (We call it the hiney-lick maneuver. - C.)
NO: jewlery YES: jewelry The root of this word is "jewel" and that doesn't change for either "jeweler" or "jewelry." The British add a syllable: "jewellery" (See also its spelling.)
NO: liberry YES: library As mentioned before, English speakers dislike two [r]s in the same word. However, we have to buck up and pronounce them all.
NO: mawv YES: mauve This word has not moved far enough away from French to assume an English pronunciation, [mawv], and should still be pronounced [mowv].
NO: mannaise YES: mayonnaise Ever wonder why the short form of a word pronounced "mannaise" is "mayo"? Well, it is because the original should be pronounced "mayo-nnaise." Just remember: what would mayonnaise be without "mayo"?
NO: nother YES: other Misanalysis is a common type of speech error based on the misperception of where to draw the line between components of a word of phrase. "A whole nother" comes from misanalyzing "an other" as "a nother." Not good. Not good.
NO: orientate YES: orient Another pointless back-formation. We don't need this mispronunciation from "orientation" when we already have "orient." (See also "interpretate")
NO: perculate YES: percolatePronouncing this word as "perculate" is quite peculiar. (Also, remember that it means ''drip down'' not ''up.'')
NO: perscription YES: prescription Same as above. It is possible that we simply confuse "pre-" and "per-" since both are legitimate prefixes.
NO: prostrate YES: prostate Though a pain in the prostate may leave a man prostrate, the gland contains no [r].
NO: realator YES: realtor As you avoid the extra vowel in "masonry," remember to do the same for "realtor," the guy who sells what the mason creates.
NO: snuck YES: sneaked I doubt we will get "snuck" out of the language any time soon but here is a reminder that it really isn't a word.
NO: spade YES: spay You can have your dog spayed but so long as she is a good dog, please don't spade her.
NO: spitting image YES: spit and image The very spit of someone is an exact likeness. "The spit and image" or "spit image" emphasizes the exactness.
NO: supposably YES: supposedly Adding -ly to participles is rarely possible, so some people try to avoid it altogether. You can't avoid it here.
NO: take for granite YES: take for granted We do tend to take granite for granted, it is so ubiquitous. But that, of course, is not the point.
NO: volumptuous YES: voluptuous Some voluptuous women may be lumpy, but please avoid this Freudian slip that apprises them of it.
