promoter

The word "promoter" has a clear lineage from Latin to modern English. It is built on the Latin verb promovere, meaning "to move forward, advance, or push into public view," which itself combines pro- ("forward") and movere ("to move"). The agent suffix -er was added in English to denote "one who does the action." Thus, the literal sense of "one who moves something forward" evolved logically into the modern meanings of a supporter, organizer, or financial backer who advances a cause, event, or commercial venture. In molecular biology, the term was adopted in the mid-20th century to describe the DNA sequence that "moves forward" or initiates the process of gene transcription.
