bæra

Böra is a verb found in Scandinavian languages, most commonly described in Swedish as meaning to be obliged to, have to, or ought to. In modern Swedish its use is largely confined to archaic, literary, or formal contexts, with the practical meaning typically rendered by the present form bör or the conditional/past form borde rather than the infinitive böra.

In historical and formal texts böra expresses obligation or normative suggestion, similar to the English should. Traditionally it can appear in impersonal constructions such as Det böra ske (It should happen) or Man böra följa reglerna (One should follow the rules). In everyday contemporary Swedish, these ideas are usually conveyed with bör or borde.

Etymology and cross-language relation indicate that böra is cognate with the Norwegian bør and Danish bør, sharing a common Germanic heritage that encodes obligation or recommendation. The semantic core is maintained across these languages, though modern usage in each language has shifted toward more common forms.

Grammatical notes: böra is considered old-fashioned or literary in Swedish, and its full paradigm is rarely used in contemporary speech. The verb’s core meaning persists in the modern auxiliaries bör and borde, which fulfill similar functions in present and past/conditional contexts. Because of its rarity outside of historical or stylistic writing, böra is primarily of interest to linguists and scholars of Swedish language history.
