Hættulegum

Hættulegum is the dative plural form of the Icelandic adjective hættulegur, which means dangerous or hazardous. In Icelandic, adjectives decline to agree with the gender, number and case of the nouns they modify; in the dative plural, many adjectives take the ending -um. Therefore, hættulegum is used when describing plural nouns in the dative case.

Examples of usage include phrases such as í hættulegum aðstæðum (in dangerous circumstances) and á hættulegum svæðum (on dangerous areas). The form is commonly found in descriptive or formal prose, safety guidelines, news reports about hazards, and literary text where nuance of danger is being conveyed.

Etymology: hættulegur is built from hætta, meaning danger, with the common suffix -legur that forms adjectives meaning “dangerous” or “hazardous.” The inflected form hættulegum follows standard Icelandic declension rules for adjectives in the dative plural.

Notes: When the noun is singular or occurs in other cases, other forms of the adjective are used, such as hættulegur (nominative singular masculine), hættuleg (feminine), or hættulegt (neuter). The exact form depends on case, number and definiteness of the noun it modifies.
