Rühmadega

Rühmadega is an Estonian comitative construction meaning “with groups.” It is formed by taking the genitive plural of the noun rühm (rühmade) and adding the comitative suffix -ga. The suffix marks accompaniment or association and is used with nouns to express that an action or situation involves other parties.

In usage, rühmadega indicates that something is done together with groups, often without an explicit preposition. It can occur in clauses such as: Me tulime rühmadega (We came with groups); Koolitus toimus rühmadega osalejate jaoks (The training was held for participants together with the groups). The form is productive for referring to multiple groups or groups as a whole. In many contexts, the preposition koos may be used as an alternative, but rühmadega is a compact, inflected form that integrates into noun phrases and clauses.

Etymology and related forms: The comitative suffix -ga attaches to the genitive form of a noun to express accompaniment. For plural nouns, this often results in -ga following the genitive plural, as in rühmadega. Other examples follow the same pattern with different nouns, enabling a range of “with X” expressions without separate prepositions.

Rühmadega is a standard feature of Estonian morphology and is commonly found in both formal and informal speech when specifying involvement of groups.
