Words that don’t exist in the english language:

L’esprit d’escalier: (French) The feeling you get after leaving a conversation, when you think of all the things you should have said. Translated it means “the spirit of the staircase.”

Meraki: (Greek) Doing something with soul, creativity, or love.

Forelsket: (Norwegian) The euphoria you experience when you are first falling in love.

Gigil: (Filipino) The urge to pinch or squeeze something that is unbearably cute.

Pena ajena: (Mexican Spanish) The embarrassment you feel watching someone else’s humiliation.

Cualacino: (Italian) The mark left on a table by a cold glass.

This should also include the word kilig. Even the word Giddy doesn’t give justice to it.
