impervious

[im-pur-vee-uhs]

adjective

incapable of being influenced, persuaded, or affected

Explanation

To be impervious to something is to remain completely unbothered by it. The word suggests a barrier that outside forces can't easily penetrate. Being impervious to criticism can keep you focused on your mission, though it may also make it harder to recognize when another viewpoint has merit.

Example

He seemed completely impervious to her concerns, refusing to change his mind.

mayhap

[mey-hap]

adverb

perhaps

Explanation

Mayhap is an old-fashioned way to say "perhaps" or "maybe." Formed from the phrase "it may happen," the word gives uncertainty a slightly playful, storybook quality. A plain "maybe" gets the job done, but mayhap adds a bit of flair.

Example

If you take the long route home, mayhap you will see the beautiful sunset over the mountains.

versicolor

[vur-si-kuhl-er]

adjective

changeable in color; of various colors

Explanation

Versicolor can describe something that's actually multicolored or just appears to change color depending on the light or angle. It's a good word for lustrous surfaces where one hue seems to give way to another as your viewpoint changes. Opals, soap bubbles, and beetle shells can all be versicolor, depending on how you look at them.

Example

The designer chose a versicolor fabric that shifted from emerald green to purple in the light.

robustious

[roh-buhs-chuhs]

adjective

boisterous; vigorous

Explanation

A robustious person or event is full of energy and hard to ignore. Imagine a rowdy celebration where the crowd keeps getting louder as the evening goes on. A robustious character certainly doesn't sit around waiting to be noticed.

Example

The robustious children ran through the yard, shouting and jumping with endless energy.

nettlesome

[net-l-suhm]

adjective

causing irritation, vexation, or distress

Explanation

A nettlesome issue is irritating enough to bother you, but it's usually not a truly serious problem. The word is related to the stinging nettle, a plant whose leaves cause an unpleasant and sometimes lingering prickling sensation when touched. A squeaky cabinet hinge can become surprisingly nettlesome once it starts getting under your skin.

Example

The nettlesome mosquitoes buzzed around our ears, keeping us from falling asleep.
