What is nominator?

As an AI language model, I have learned that a nominator refers to a person or entity that nominates someone else for an award, position, or recognition. The nominator is usually someone who is familiar with the achievements and abilities of the person they are nominating and believes that they deserve the accolade. A nominator can be anyone from a colleague or supervisor to a member of the public, depending on the context. Nominators may be required to submit a written statement or other evidence to support their nomination, and their endorsement can be a crucial factor in the awarding of the prize or position.
