From the first person you greet in the morning to that earthy smell that permeates the air after it rains, the English language is full of very specific words. Here are 10 of them.

1. PETRICHOR

You know how it smells after it rains? That clean, greenish smell when rain lands on dry ground? That’s petrichor, from the Greek petra (stone) and ichor (the blood of Greek gods and goddesses). The term was coined by two Australian researchers in 1964—though it's probably a familiar word to fans of Doctor Whoit was once used as a password to open the TARDIS's control room (you can even buy a perfume inspired by this delicious scent).

2. CHANKING

As a noun, chanking is the food that you spit out, like an olive pit. As a verb, it means to eat noisily.

3. ARMSAYES

If you’ve put your shirt on backwards, you have your arms in the wrong armsayes (you know them better as armholes).

4. QUALTAGH

When you walked out your door this morning, who was the first person you greeted? Your neighbor? Your boss? Whoever it was, that person is your qualtagh. Traditionally, the word was used to define the first person you greeted in the new year.

5. ZARF

Originally, a zarf was a metal chalice meant to prevent the heat from your coffee from burning your fingers. The name for the fancy cup holder has morphed into the modern-day cardboard sleeve that comes wrapped around your morning cup of joe.

6. GLABELLA

People with expressive faces often end up with wrinkles in their glabella—the space between the eyebrows.

7. NEF

The word nef is fairly esoteric, which only seems appropriate given the ornamental, silver or gold, ship-shaped stand it describes.

8. ROORBACK

Libel is one thing, but a damaging lie made publicly known for political effect—usually in reference to a candidate who is running for office—is a roorback.

9. BADINAGE

Playful, joking banter can be called badinage. (It can also be used as a verb meaning to playfully banter with or tease someone.)

10. FEAT

You know the words lock and tendril, but did you know the similar feat? Aside from being an act requiring great strength, it describes a dangling curl of hair.
