There's now a word for nails on a blackboard - but it's not in English
You might not have heard of "grima", but you have almost certainly felt it.
It's a word to describe the feeling we get when we hear the sound of fingernails on a chalkboard, or a knife scratching a plate.
Now psychologists in Spain are suggesting it should be considered its own emotion.
Describing what "grima' means to them, Spanish speakers said it was an "unpleasant sensation", "shivering", "sounds" and "repulsion".
We're not the only culture who doesn't have this word
Some societies don't even have a word for worry, whilst others have 15 words for fear.
Prof Vyvyan Evans, who specialises in language and communication, tells Newsbeat this phenomenon relates to something called "untranslatable words".
"Emotions can be expressed in a range of ways, and emotions are universal," he says.
Professor Evans says the reason English-speakers don't have a word for "grima" is because "languages reflect their culture and words help to reinforce culture too".
But this doesn't mean that a particular culture is better or worse at expressing an idea.
It's not all about the actual words we speak
"Language is very adaptive," says Prof Evans.
"There is a range of ways in which we express emotion.
"In face-to-face spoken interaction, between 60% and 70% of our emotional expression actually comes, not from language, but from non-verbal communication.
He says the tone of your voice, or how high or low your pitch is, can also affect how you communicate and express your emotions.
"The face can produce over 10,000 expressions, many of which are associated with emotional experience," he adds.
So, although we don't have an English word for "grima", we can all recognise the horrible faces you make when someone drags their nails down a blackboard.
