imposui

Imposui is the Latin perfect active indicative form in the first person singular of the verb imponō (also spelled imponere), meaning to place on or to impose. In this form it expresses a completed action by the speaker, either physical placement—placing one object on another—or figurative imposition, such as imposing a burden, duty, or obligation.

From the prefix in- meaning “upon” and pōnō meaning “to place,” the verb has the standard principal parts imponō, imponere, imposuī, impositum. Imposuī corresponds to “I placed” or “I have placed.” The third-person perfect singular is imposuit, and the supine or participial form is impositum.

Usage: imposui is used when the speaker describes a completed act of placing something onto a surface or of imposing something on someone. Like other verbs of placement, it governs a direct object in the accusative for the thing placed, and the location or recipient may be expressed by a prepositional phrase or a dative, depending on meaning.

Relation to related forms: imposuit (he placed on) is the corresponding third-person form; impositum is the supine/participle used to form compound constructions such as impositum (having been placed). In dictionaries, imposui is listed as the perfect form of imponō/imponere.
