Omissae

Omissae is a Latin term meaning "omissions" and is used as a plural noun or as a descriptive label in scholarly and liturgical contexts. The word derives from the verb omittere, to send away or to omit; the feminine plural form omissae is commonly used in Latin texts and in reference works to indicate items that have been left out.

In textual criticism and manuscript studies, omissae refer to passages, words, or lines that are absent in a manuscript or edition. Editors may annotate omissae when a scribe has omitted material or when later corrections restore or revoke an omission. The standard critical apparatus may signal omissions with terms like "omiss." or "omissae" in notes indicating lacunae or deliberate excisions.

In liturgical books, omissae denote prayers or directives that are omitted under certain conditions. For example, rubrics may indicate omissae when a feast prescribes omitting an optional antiphon or versicle. The designation helps readers know when to skip elements in the service, depending on rite, season, or local practice.

In textual resources, "omissae" may appear in scholarly apparatus, catalog entries, or editorial prefaces to identify omitted material in the source text.

Because of its Latin origin and specialized usage, omissae appears primarily in academic, liturgical, or manuscript contexts rather than everyday language.
