الْوَهْمُ
The proposed faculty that apprehends a particular meaning associated with sensed objects but not directly sensed as a color or sound.
One classical example concerns recognizing friendliness or hostility from another person's behavior. Such relations are not sensed in the same way as color, though we may infer them from circumstances.
The technical term wahm (estimation) does not simply mean a false delusion here; it names a theory of particular non-sensible significance.
An expression or gesture alone does not justify certainty about another person's intentions. The force of the evidence and the possibility of error must be assessed separately.
