8th10th

8th10th is a relatively obscure term used in informal writing to refer to a combined designation for the eighth and tenth items in a sequence, or to a range spanning those positions. Because it lacks a formal definition, its precise meaning depends on context, and it is often encountered only in specific communities, projects, or datasets.

In bibliographic, archival, or cataloging contexts, 8th10th may signal a range (8th through 10th) or a two-part edition where the eighth and tenth components are linked. In software or media projects it can serve as a product label or version tag that pairs two installments. When the intention is to indicate a range, the conventional notation 8th–10th or 8th to 10th is clearer and widely understood; without punctuation, 8th10th can be ambiguous.

Because 8th10th is not standardized, readers should seek contextual cues such as surrounding text, punctuation, or accompanying metadata to interpret it correctly. If clarity is essential, spelling out "eighth through tenth" or using an explicit range is recommended. See also: eighth, tenth, range notation such as 8th–10th.
