ilgas

Ilgas is a Lithuanian word that primarily functions as an adjective meaning "long" or "lengthy." It is used to describe physical dimensions, distances, time spans, or abstract extents. In usage, it appears before nouns in phrases such as ilgas kelias (a long road) or ilgas laikotarpis (a long period), and its form changes according to gender, number, and case in the standard Lithuanian inflection system.

Linguistic notes: As with other Lithuanian adjectives, ilgas inflects to agree with the noun in gender and number and is declined across cases. The masculine singular form is ilgas, while feminine and neuter forms adapt to the noun they modify. The word’s semantic range includes both concrete and metaphorical senses of length, including distances and durations.

In addition to its adjectival use, ilgas may appear in compounds and in poetic or idiomatic expressions, where it contributes the sense of length or extent. The term is part of the broader Baltic language family and has cognates and related forms in related languages.
