wisenheimer

[wahy-zuhn-hahy-mer]

noun

a smart aleck who makes overly clever, obnoxious remarks

Explanation

A wisenheimer is someone who can't resist making smug or overly clever remarks. The word became popular in American English as a playful label for the class clown or wise guy. Every group seems to have at least one wisenheimer who's always ready with a comeback.

Example

Every time the teacher asked a question, the wisenheimer in the back row had a sarcastic comment.

rebarbative

[ree-bahr-buh-tiv]

adjective

causing annoyance, irritation, or aversion

Explanation

Something rebarbative causes irritation or dislike instead of drawing people in. Based on the French word barbe, meaning "beard," it evokes a hostile "beard-to-beard" confrontation. From harsh words to grating sounds, rebarbative things have a way of rubbing people the wrong way.

Example

His rebarbative behavior and constant grumbling made it very difficult for the team to work together.

loll

[lol]

verb

to hang loosely; droop; dangle

Explanation

To loll is to dangle or droop, like a dog's tongue hanging out or a person's arm dangling over a seat. The word paints a picture of something resting slack instead of being held upright. Like many words that seem to mimic the actions they describe, loll has a sound that feels as loose and unhurried as its meaning.

Example

Tired after a long shift, he let his arms loll over the side of the sofa.

corrigendum

[kawr-i-jen-duhm]

noun

a formal correction of an error, especially one in print

Explanation

A corrigendum is a formal notice of a corrected error, particularly in a published work. Even carefully edited books and articles occasionally require a correction after publication. A well-placed corrigendum helps set the record straight.

Example

The journal published a corrigendum to fix the spelling mistake found in the lead researcher's name.

bolster

[bohl-ster]

verb

to support or strengthen

Explanation

To bolster is to give support or add strength to someone or something. The word's use as a verb is derived from its noun form, which is a type of long pillow that physically supports the body. A bit of encouragement can bolster confidence when it matters most.

Example

Strong pillars were added to the old foundation to bolster the weight of the new roof.
