greitojo

Greitojo is the genitive singular masculine form of the Lithuanian adjective greitas, meaning fast, quick, or rapid. In Lithuanian, adjectives change form to agree with the noun they modify, and the greitojo form appears specifically when the modified noun is in the genitive case in masculine gender. As a result, greitojo is not a standalone word with its own meaning; it functions as a grammatical form used in attributive phrases.

In practice, greitojo is most commonly seen in compound noun phrases that describe a characteristic of another noun, particularly in technical or policy contexts. A typical example is greitojo transporto sistema, translated as rapid transit system or fast transportation system. In such phrases, greitojo signals that the noun it modifies is related to speed or rapid operation, while the noun (for example, transporto) remains in the genitive case to express a dependent relationship.

Usage notes:

- Greitojo is usually written in lowercase unless it begins a sentence or appears in a context where capitalization is required by style.

- It functions as part of a larger noun phrase rather than as an independent lexeme with separate meaning.

- The general adjective forms of greitas (and related declensions) cover other cases and numbers, with greitojo representing the masculine genitive singular.
