Speech naturally involves breathing, pausing, and resuming. A breath span (imtidad nafasī) refers to a manageable extent of speech in relation to this natural capacity. It may be comparatively long or short.
Movement from one pause to another can organize the listener’s experience. An extended clause may develop an argument patiently, whereas short segments can create concentrated emphasis and urgency.
A necessary distinction: this is a principle of natural expressive span, not a fixed measurement of seconds or a claim that all reciters breathe identically. Recitations may differ in pace while preserving the intended relationships in the discourse.
