groepeerde

Groepeerde is a Dutch verb form that marks the past tense of the verb groeperen, meaning to group or cluster. It is the simple past tense used with a singular subject, as in De onderzoeker groepeerde de deelnemers in drie categorieën. The corresponding present tense is groepeert, and the past participle is gegroepeerd, which is used in perfect tenses (de gegevens zijn gegroepeerd).

Etymology and form: groeperen combines the base group concept with the -eren verb suffix, forming a regular Dutch verb. The simple past takes the -de ending for most singular and plural subjects in standard narrative past, yielding groepeerde for third-person singular. The past participle gegroepeerd is used with hebben or zijn, for example: De respondenten zijn gegroepeerd op leeftijd.

Usage context: groepeerde commonly appears in writing about data analysis, research methods, sociology, and project documentation, where items or people are organized into groups, clusters, or categories after review or processing. It can describe actions taken in the past, whether sorting data, classifying respondents, or organizing information.

Relation to related forms: while groepeerde refers to a past action by a single subject, groepeerden would be used for plural subjects ("zij groepeerden"). Gegroepeerd (past participle) is used to form compound tenses, such as hebben gegroepeerd.
