NEW YORK (AP) — Donald Trump’s New York criminal trial is full of terms you don’t typically hear in a courtroom.

Centering on allegations Trump falsified his company’s records to conceal the nature of hush money reimbursements, it’s the first ever criminal trial of a former U.S. president and the first of Trump’s four indictments to go to trial. It also has some unique terminology.

Here are some examples:

HUSH MONEY

DEFINITION: According to Merriam-Webster, it’s money paid so that someone will keep information secret. In other words, money that a person pays someone to hush up something.

EXAMPLE: Three payments that prosecutors say were made on Trump’s behalf to bury marital infidelity claims during his 2016 presidential campaign. They are the National Enquirer’s $30,000 payment to a Trump Tower doorman and $150,000 payment to former Playboy model Karen McDougal, and the $130,000 that Trump’s then-lawyer and fixer Michael Cohen arranged to pay porn actor Stormy Daniels.
