Ilusad

Ilusad is primarily the Estonian nominative plural form of the adjective ilus, which translates to "beautiful" in English. As a grammatical form, ilusad is used to modify or describe plural nouns (for example, ilusad lilled — "beautiful flowers") and appears in both attributive and predicative positions in sentences. Estonian adjectives inflect for number and case; the -d ending marks the nominative plural in standard modern Estonian.

Beyond its grammatical role, ilusad appears in everyday speech, literature, advertising and other cultural contexts where plural descriptions are required. Because the word is an ordinary adjective form rather than a lexical root, it is often encountered in phrases rather than as an independent entry in dictionaries.

The term can also serve as a surface form in names, titles or informal expressions, though such uses are context-dependent and do not change its basic grammatical identity. When discussing or translating Estonian texts, recognizing ilusad as the plural of ilus aids correct parsing and agreement with plural nouns.
