Ballot, manifesto, party, pledge, swing...
You'll be hearing words like these pretty often between now and the general election on 12 December 2019.
During the campaign the different political parties will be working hard to win the vote of adults across the UK.
It can be a lot to take in, so Newsround's got this special list of election buzzwords for you to keep handy and impress your friends with!
Ballot paper - the piece of paper on which you cast your vote, by marking an X in the box next to the name of the person you want to win.
Ballot box - the sealed box in which you put your ballot paper after you've voted.
By-election - a one-off election that happens in between general elections, usually when an MP in a certain area has died or resigned.
Candidate - a person who is running in an election, usually representing a certain political party.
Coalition - when two or more parties join together to make a government (when no party has a majority of the seats in the House of Commons). This is what the Conservatives and Liberal Democrats did after the last general election.
Constituency - the area that your elected MP represents. There are 650 constituencies in the UK (and, as a result, 650 MPs).
Deficit - the difference between what the government collects in taxes and what it spends. Cutting the country's deficit is a key talking point.
Electoral register - the list of everyone who is registered to vote. You need to be on it to be able to vote on 8 June.
First past the post - is the voting system we use in the UK. Despite the name, there is no actual 'post', it just means that the candidate with the most votes wins.
Government - the government runs the country and is usually formed by the party that wins the election, or by a coalition.
House of Commons - the elected bit of Parliament where all the MPs who are voted into office have their own chamber to vote on laws and debate. You can tell if you're watching the House of Commons if people are sitting on green benches.
House of Lords - unlike MPs, Lords aren't elected but usually chosen for their experience. They do things like consider new proposed laws and check the work of the government. You can tell if you're watching the House of Lords if people are sitting on red benches.
Hung parliament - if no party gets a majority (more than 50%) of seats then we have a hung parliament.
Kingmaker - if there's a hung parliament then smaller parties might be able to play 'kingmaker' to the bigger parties who need extra MPs to make up a government.
Landslide - a landslide is when a party wins loads more seats than the nearest rival party. Experts think it's unlikely this time.
MP - stands for Member of Parliament. Each of the 650 UK constituencies has an MP who represents his or her area's interests in the House of Commons.
Majority - this means one party winning more than 50% of seats in the House of Commons that allows them to form a government (the magic number is 326).
Manifesto - a list of a party's ideas and policies, outlining what it'll do if it wins the election.
Marginal seat - a constituency where different party's support is very close and it's hard to predict who will win.
Swing - used to describe how much of a change in support there is from one party to another.
Opposition - the political parties with the most number of seats are The Opposition. They sit opposite the government in the House of Commons. The leader of the opposition party with the most seats is called the "Leader of the Opposition".
Parliament - is where new laws get debated and agreed. Parliament is made up of two 'houses' - the House of Commons and the House of Lords - and also, officially, the Queen but she doesn't get involved in decision-making.
Party - we're talking political party here, which refers to a group that have common political goals. Most MPs belong to a political party.
Pledge - a pledge is a promise from a political party.
Policy - is the name for a plan of action from the party.
Polling station - is the place where you go to cast your vote - usually somewhere local to where you live, such as a school.
Prime Minister of the United Kingdom - the person who is leader of the country and moves into 10 Downing Street. It's usually the leader of the biggest political party.
Referendum - a type of vote where voters are given the chance to decide on a major issue, by voting yes or no. This type of election doesn't elect any people, it simply lets politicians know how the country thinks about a single issue.
Returning officer - the person chosen to make sure the area's vote goes smoothly and is done fairly. He or she will also announce the result.
Seat - when a candidate wins and becomes an MP, they win a 'seat' in the Houses of Parliament.
Spoilt ballot - when a voter hasn't voted properly on their ballot paper, such as by leaving it blank or writing more than one cross. Spoilt votes don't count towards the final result.
Term - a bit like a term at school or university, it means the period of time between general elections. MPs are elected to serve for one term.
Turnout - the number or percentage of people who actually turned out to vote.
