parachrema marks an event as occurring at once, directly following the action or circumstance described.

The adverb marks immediate sequence or onset: physical restoration follows a touch or command, death or judgment follows an act, and events such as a rooster’s crow, opened prison doors, or a fig tree’s drying occur without delay. It can also qualify an anticipated appearance, as in Luke 19:11.

1. At once, without delay · dominant

   The adverb marks what follows directly in the narrated sequence. In Acts 3:7 the APB renders the strengthening of the man’s feet and ankles after he is raised by the hand; in Luke 13:13 it renders the woman’s restoration after hands are laid on her; and in Acts 16:26 it accompanies the opening of the prison doors and release of bonds after the earthquake. The same immediate timing is applied to judgment or death in Acts 12:23 and Acts 5:10, and to the expected appearance of God’s kingdom in Luke 19:11.

In the Anselm Project Bible: The APB variously presents the adverb with “instantly,” “immediately,” “at once,” and “suddenly” across these verses. Those renderings confirm the verses’ immediate temporal sequence rather than establish separate meanings.
