COM((Am,Ai), (Bm,Bi)) = (COMm(Am,Bm), COMi(Ai,Bi)) = (CONCEPT-MERGE(Am,Bm), SUPERPOSE(Ai,Bi))
Explanation:
The images Ai and Bi are combined by superposition. At the same time, the
conceptual merge of the meanings Am and Am becomes the meaning
of the resultant new icon.
For example, the combination of a diagonal line icon with
a road icon would result in the superposition of the two icons and the conceptual merge of
no and road,
resulting in the no-entry
icon.
