Ījāz al-ḥadhf extends from individual clause elements to whole clauses and multiple implied events. The omitted material can be a possessive term, descriptor, object, condition, answer, narrative stage or action implied by a familiar occasion.
The crucial factor is evidence for the omission—reason, surrounding discourse, causal relations, custom or the beginning of an action. One must then identify the rhetorical gain: economy, narrative speed, vivid impact or directed audience attention.
The next topic, iṭnāb, examines purposeful expansion: extra wording used to clarify or enhance the meaning rather than to create empty verbosity.
