Nonanchor

Nonanchor is a term used in several disciplines to describe an element that does not function as an anchor—a fixed reference point, attachment, or linking element. There is no single formal definition, and usage varies by field.

In graphs and layout algorithms, an anchor node is a fixed point used to stabilize positions; a nonanchor node is any node not designated as anchor, and may be treated as movable or dependent on anchors during layout computations.

In information architecture and discourse analysis, anchors establish references within a text or conversation. Nonanchor items are content that does not establish or rely on a reference frame; they provide context or peripheral information.

In web design and HTML, an anchor refers to a hyperlink, created with an anchor tag. Nonanchor content refers to sections or elements that do not function as links.

In mechanical or civil engineering, anchors secure components to substrates; nonanchors are parts that are not fixed to the substrate and may be detachable or free-form.

Because nonanchor is not a standardized term, its precise meaning must be inferred from context and field-specific definitions. Related terms include anchor, anchored, anchoring, and non-anchored.
