Single/composite describes the structure of the compared terms. Enfolded/separated describes the ordering of several comparisons. Taswiya/jamʿ distinguishes several subjects sharing one model from one subject receiving several models. Representational/non-representational concerns how the shared respect is derived, and detailed/condensed whether it is explicitly mentioned.
The central principle is to keep the basis of each division consistent. An indicator relevant to one division should not automatically be taken as evidence for another. Several nouns in a line do not necessarily create a unified composite scene.
The next section examines familiar, immediately apparent versus remote, unusual resemblances, where the question becomes how readily the audience moves from subject to comparison term.
