A more thorough explanation:

A money-market account is a type of bank account that pays interest on the balance. It is similar to a savings account, but usually offers a higher interest rate. However, there are limits on the number of transactions you can make each month.

For example, let's say you deposit $10,000 into a money-market account that pays 2% interest. Over the course of a year, you would earn $200 in interest. However, if you try to withdraw money from the account more than six times in a month, you may be charged a fee.

Money-market accounts are a good option for people who want to earn interest on their savings but still have access to their money. They are also considered a low-risk investment because they are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per account.
