Kataloogis

Kataloogis is the inessive singular form of the Estonian noun kataloog, meaning "in the catalog." It is used to indicate that an item is located inside a catalog or is listed there.

Origin and grammar: The noun kataloog comes from the same root as English catalog and French catalogue, via Latin catalogus. In Estonian, the inessive case (-s) marks location, so kataloogis in the singular. The corresponding plural form is kataloogides, meaning "in the catalogs."

Usage: The phrase is common in libraries, online catalogs, product catalogs, and database interfaces. Examples: "Toode on kataloogis 12345" or "Kaupade kirjeldused on kataloogis." In digital catalogs it often appears in search results and item descriptions to show where an entry can be found.

Notes: Kataloogis is a neutral, standard grammatical form and not a separate lexical item. It is one of several locative forms in Estonian and is used whenever the speaker wants to reference something inside a catalog. See also kataloog, kataloogides.
