ومقام الإيجاز يباين مقام خلافه
The station of brevity differs from its contrasting station.
The source contrasts ijaz with itnab and musawah. Ijaz conveys the intended meaning economically; itnab adds useful amplification; musawah maintains an apt proportion between words and communicated meaning.
ModeExample of a fitting context
BrevityA short but sufficient answer to an unambiguous question
AmplificationFurther explanation or confirmation needed to remove doubt
Proportional expressionA balanced statement suited to the point
Amplification is not mere verbosity, and brevity is not a virtue when it obscures the intended meaning. Purpose and situation govern the choice.
