One who anchors; a person or device that serves as an anchor or provides anchoring capability.
From 'anchor' plus the agent suffix '-er' (one who does the action). This word can refer either to a person who operates or deploys anchors, or metaphorically to someone who provides stability or support.
In broadcast journalism, news anchors are literal 'anchorers'—they provide stability and consistency to a show, and the term was chosen deliberately because they're supposed to be the reliable, trustworthy foundation of the broadcast!
