To analyse waṣl correctly, proceed in this order:
1. Decide whether each clause functions as assertion or non-assertion.
2. Ask whether the second is merely confirmation or clarification, in which case faṣl may be appropriate.
3. Identify the rational, estimative, or imaginal bond between subjects and predicates.
4. Explain whether wāw adds appropriate coordination or removes ambiguity.
5. If the clause is circumstantial, analyse its pronoun, wāw, type and tense separately.
Qaṣr concerns restriction of meanings, while faṣl and waṣl govern how statements are separated or combined. The next chapter, ījāz, iṭnāb and musāwāh (الإيجاز والإطناب والمساواة), asks how the amount of wording relates to the meaning to be conveyed.
