Belarusian to Icelandic: choose the case with the target verb
A direct object does not guarantee one case
Belarusian and Icelandic both use case forms, which can make a grammatical comparison feel straightforward. The useful question, however, is not simply which Belarusian ending corresponds to which Icelandic ending. The Icelandic verb can determine a case that is not predictable from a broad label such as person affected by the action.
Eiríkur Rögnvaldsson’s University of Iceland paper contrasts Ég sé hann, I see him, Ég hjálpa honum, I help him, and Ég sakna hans, I miss him. The three references to him have different case forms. In a Belarusian request involving another person, selecting the Icelandic verb and selecting that person’s form must be treated as a connected decision.
Do not assume that two Icelandic verbs with similar practical meanings take identical complements. If a translation is revised to use a different verb, review the dependent pronoun or noun again. Retaining its previous form can leave a sentence with individually suitable words that no longer fit together grammatically.
Case does not make word order irrelevant
The Belarusian UD description identifies nominative subjects and also genitive subject phrases under some conditions. Icelandic likewise has constructions whose subjects are not nominative. A target phrase should therefore not be corrected merely because the person central to the message has an oblique form.
At the same time, visible case does not mean that the target words can be arranged arbitrarily. The Icelandic paper discusses restrictions on where noun phrases may occur, including non-nominative subjects. When a Belarusian sentence places important information first, preserve its communicative purpose through an actual Icelandic construction rather than copying the sequence on the assumption that endings will repair it.
This is useful for brief reports of needs, experiences and completed work. Establish who experiences the condition, which item is affected and what the predicate says about them. Then inspect the Icelandic clause as a unit. Source prominence, grammatical subject and acting person are related questions, but they are not always the same question.
Descriptions may need a separate linking verb
Belarusian nominal clauses can be formed without an overt copula. Icelandic uses vera in descriptions, identification and location constructions. A translated Belarusian status line may therefore become longer through required target grammar rather than through added factual content.
Keep the tense of that description tied to the source. A report of how something was before a repair differs from a statement of its condition now. Check the Icelandic linking construction together with the adjective or location phrase, rather than approving the descriptive word and overlooking the time supplied by the verb.
A practical review for this direction
After translating a Belarusian message into Icelandic, revisit any place where you changed the target verb or moved a participant for emphasis. Those edits can affect the surrounding case construction. Similar-looking grammatical categories provide a useful starting point, but the selected Icelandic predicate decides how its sentence is assembled.
Keep the Icelandic letters and accents when saving a useful phrase. More importantly, save enough of the phrase to include the governing verb: a detached pronoun form is a poor model for a later message whose action may require a different case.
