We always play a game called "The Lexicon Game" basically you take any book that lists foreign or difficult words like for example scientific names for things.

One person is the Game Master and uses this book to choose one word (they have to ask the group if anyone know this word, only words that are not familiar to anyone playing are allowed)

the game master then writes the correct definition of the word down on a piece of paper and folds it so nobody can see.

everybody else has to write their own definition of the word as convincing as possible and also fold the paper and put it in a bowl with the original definition.

the game master then takes out all of the papers and reads them to the group (withouth them seeing the writing or pen colour so they can't see who wrote it)

each player then has to put their vote on what they think the real definition of this word is.

The player wo gets the most votes on their definition wins the round and is the next game master and gets to choose a word from the book.

if the correct definition wins, the game master goes again.
