The term 'ACT THE MIDDLEMAN' can be broken down into two crossword solutions: RESELL (6 letters) and LIASE (5 letters). RESELL refers to the act of buying goods or services from one party and then selling them to another. This is a common practice in the business world, as it allows companies to acquire goods or services at a lower cost than if they were to purchase them directly from the original source. LIASE, on the other hand, is a term used to describe the process of establishing and maintaining communication between two parties. This is often done by a third party, such as a middleman, who acts as a liaison between the two parties. In this case, the middleman would be responsible for facilitating communication between the two parties and ensuring that all agreements are met.
