ettårigt

Ettårigt is a Swedish adjective meaning one year old. It is the neuter singular form of the adjective ettårig and is used to describe nouns of neuter gender that have an age of one year. The term appears most often in descriptive phrases such as ettårigt barn or ettårigt föl, where the noun is directly modified by the adjective.

In practice, ettårigt describes age in a compact, attributive position before a neuter noun. It is common in contexts like veterinary notes, care records, and product descriptions or literature that requires concise age labeling. For predicative use—where a person or animal is described after a linking verb—Swedish more commonly uses a periphrastic construction such as ett år gammal/ett år gammalt rather than ettårig.

Spelling and grammar note: ettårigt is the neuter singular inflection of the adjective ettårig. The base form ettårig is used before non-neuter nouns or in certain stylistic contexts, while plural forms and other gendered forms follow standard Swedish adjective agreement rules (for example, ettåriga barn in plural). The construction remains primarily descriptive and is especially frequent in formal, clinical, or archival texts.
