Lingvistikaj

Lingvistikaj is an Esperanto adjective used to describe things related to linguistics when the noun it modifies is in the plural. In Esperanto, adjectives do not mark gender and they agree with the noun in number; to indicate plurality, the ending -j is added. Therefore lingvistikaj corresponds to “linguistic” or “linguistics-related” in the plural sense.

The form is derived from the root associated with linguistics. The singular form is lingvistik-a, and the plural form is lingvistikaj. It appears in many phrases such as lingvistikaj studoj (linguistic studies), lingvistikaj teorioj (linguistic theories), or lingvistikaj projektoj (linguistic projects). As a general-purpose modifier, it can describe analysis, data, tools, or debates that pertain to linguistics, when the described noun is plural.

Lingvistikaj is not a standalone noun; it functions as an adjective. In titles, headings, or list items, it may appear before a plural noun to indicate that the topic is linguistic in nature.
