détablissent

Détablissent is a conjugated form of the French verb détablir, appearing as the third-person plural of the present indicative (ils détablissent) and of the present subjunctive (qu'ils détablissent). The verb détablir is formed from the verb établir (to establish) with the prefix dé-, a pattern that in various Romance languages signals reversal or undone action. Consequently, détablir has carried meanings related to undoing establishment, removing a standing arrangement, or detaching something from a fixed position; however, the precise sense depends on historical usage and context.

In contemporary standard French, détablir is rare, and writers often prefer établir or employ other constructions to express related ideas such as negation, removal, or destabilization. Détablissent as a form occurs primarily in literary, historical, or formal registers, and is encountered mainly in older texts. Orthographically, the form is identical for both the indicative and the subjunctive in this person and number; the mood is inferred from the syntactic context rather than the spelling, though qu'ils détablissent would signal the subjunctive mood.
