periódusra

Periódusra is the dative singular form of the Hungarian noun periódus, meaning "to the period" or "for the period." In Hungarian grammar, the suffix -ra (with vowel harmony) marks direction toward or applicability to a time interval, and is attached to nouns to indicate the temporal target of an action or assessment. The form periódusra is therefore used when referring to a specific period as the object of a verb or the focus of a statement.

Periódusra appears most often in formal or technical language, such as research reports, statistical summaries, scheduling notes, and regulatory texts. Examples: "Az adatok az adott periódusra vonatkoznak." "A szabályozás a periódusra érvényes." "A vizsgálat az 1800–1900 közötti periódusra összpontosít." In such contexts it helps to specify the time frame to which statements, requirements, or results apply.

Etymology and related forms: periódus is a loanword from Latin periodus, via Greek periodos, and has a broader meaning of a time interval or segment within a sequence. In Hungarian, időszak is often used for everyday time periods, while periódus retains a more technical or formal flavor. The plural dative form is periódusokra, and related adjectives include периодushoz kapcsolódó or periódusra vonatkozó.
