számolniuk

számolniuk is the third-person plural possessive infinitive form of the Hungarian verb számolni, which means to count. It is formed by taking the infinitive számmolni and adding the possessive suffix -uk, which marks that the subject of the infinitive is ők (they). This non-finite form is used in clauses where the subject performing the action is specified as they.

In usage, számolniuk functions in constructions that express obligation, necessity, or intention, typically after a modal verb or a similar auxiliary. The most common pattern is meg kell számolniuk or kell számolniuk, meaning they must count. In these cases the suffix on the infinitive signals who is responsible for the action, while the main verb governs mood and tense.

Examples:

- Meg kell számolniuk az adatokat. They must count the data.

- A feladat megoldásához számolniuk kell a tételeket. For solving the task, they have to count the items.

Semantics and style note:

számolniuk is a formal, grammatical construction often found in written or instructional Hungarian, especially in guidelines, manuals, or official sentences describing required actions. In everyday speech, speakers might use a simpler periphrase, such as "ők kell, hogy számoljanak" or rephrase the sentence to avoid the fused infinitive.
