marker
Indicates a position
A marker is something that marks—indicates, identifies, or sets apart.
The most common meaning is a felt-tipped pen for writing or drawing: She grabbed a marker and wrote on the whiteboard.
Markers also indicate position or boundaries: a mile marker, a grave marker, a bookmark.
In genetics, a marker is a gene or DNA sequence used to identify a chromosome or trait.
To put down a marker is to stake a position or signal intent.
