Emacitus: The desire to buy things from Latin.
The English version of this word ‘Emacity’ fell out of use at the beginning of the 20th Century. This was replaced by less beautiful terms to describe the same thing, such as shopaholic, consumerism and retail therapy.
Emacitus derives from the even older Proto-Indo-European word Em
You may have heard of the Latin phrase Caveat Emptor – which means buyer beware.
There are many other modern words related to money, trade and transactions that contain the root word Em:
Ransom (which comes from the Old French word raenson)
Exempt: comes from the Latin word ex-emptus which means ‘Not for sale’.
Embezzlement: is tampering with documents to steal money.
