You might be hearing the word Mercosur a lot in the news headlines over the past while. But what does it mean? RTÉ's Juliette Gash came into the news2day studio to chat to Florence and break it all down for us - watch the explainer above.
The big story is all about a trading deal between the European Union (EU) and a group of countries in South America collectively known as the Mercosur. The word Mercosur comes from Mercado Comun del Sur, which means Southern Common Market in English.
It was founded over 30 years ago by the countries Argentina, Brazil, Paraguay and Uruguay. It has been a really long and complicated process, but talks have been ongoing since 1999 between the EU and these four countries.
It's really important because there are around 700 million people living in these four countries. So the EU, and many European leaders, really want to use this deal to increase trade with countries outside of the USA.
While some EU countries are happy, others like Ireland do not want to back the deal with farming groups especially worried. Taoiseach Micheál Martin and Tánaiste Simon Harris have confirmed that Ireland will vote against the Mercosur free trade agreement.
