The term 'FORERUNNER' can be defined as a HERALD, procaimer, or precursor. A HERALD is someone who proclaims or announces something, often in a formal or official capacity. This could include announcing the arrival of a monarch or other important figure, or making a proclamation on behalf of a government or other authority. A procaimer is someone who publicly declares or proclaims something, often with the intention of persuading others to accept it. This could include making a public statement about a political issue or advocating for a cause. Finally, a precursor is someone or something that precedes or comes before something else, often serving as an indication of what is to come. In this context, a FORERUNNER could be seen as a combination of all three roles, acting as a HERALD, procaimer, and precursor.
