sublining

Sublining is a rarely used term whose precise meaning varies by field. It is not widely defined in major dictionaries, and its usage is not standardized. The word is typically formed from sub- and line, suggesting a line positioned beneath something else. Because it is not consistently defined, different disciplines have adopted different senses.

In typography and page layout, sublimines or sublimining could refer to a secondary line of text placed beneath a primary line, such as a caption, footnote indicator, or editorial note associated with that line. This usage is uncommon and may appear only in niche typographic workflows.

In data visualization or technical drawing, subline may denote an auxiliary line that lies below a primary data line, for example a threshold, tolerance band, or reference line used to contextualize the main series. This interpretation emphasizes relational positioning rather than a separate content type.

In cartography or surveying drafts, sublimines can describe subordinate lines that represent ancillary boundaries or features beneath the main contour or boundary line. In these contexts, sublines help convey additional information without cluttering the principal map feature.

In software or UI design, the term could be used informally to describe a secondary line of information under a primary label, though this would be informal usage rather than a formal standard.

Because subliming has no universally accepted definition, readers should consult field-specific glossaries or style guides when encountering the term in professional work. See also: subline, baseline, annotation, caption, line graph.
