passiveadverbials

Passive adverbials, or passive adverbials, refer to adverbial expressions that accompany passive clauses and provide information about how, when, where, or by whom an action is performed. They are related to, but distinct from, adverbials in active clauses, because passive syntax can influence their availability and placement.

Common types include agentive by-phrases, instrumental or manner adjuncts, and non-agential adverbials that describe the event. Examples illustrate the range: The ball was thrown quickly. (manner) The ball was thrown yesterday. (time) The ball was thrown by John. (agent) The door was opened with a key. (instrumental) The door was opened in the morning by the manager. (place and agent) In many languages, these adverbials can appear before or after the verb phrase, with order driven by focus, style, or discourse.

Functionally, passive adverbials supply circumstantial information about the event without reasserting the agent, especially when the by-phrase is absent or suppressed. They also help speakers adjust emphasis, for example by highlighting the manner or the timing of the action.

Cross-linguistic patterns vary. Some languages favor explicit agent marking in passives and restrict certain adverbial placements, while others rely more heavily on adverbials to convey agent, instrument, or other circumstantial details. The label passive adverbials is used differently across grammars, and some analyses treat by-phrases as a separate class from adverbials.
