Stage 1: The evidential force of circumstances is likened to the communication performed by actual speech.
Stage 2: The underlying notion of speaking is borrowed for that nonverbal manifestation of meaning.
Stage 3: The figurative action is then expressed in the past-tense form “naṭaqat” and predicated of the situation.
The verbal metaphor thus rests on an earlier consideration of the action-meaning, which is why it is termed dependent. Merely observing that “situations do not speak” misses the intellectual mechanism.
