 Hypothetical syllogisms whose premises share an incomplete part are perhaps best understood in opposition to two types of purely hypothetical syllogisms discussed above, namely those consisting of a pair of disjunctive premises and those consisting of a disjunctive and a conditional premise. In both cases, the shared part was a whole proposition. Syllogisms involving hypotheticals that share an incomplete part are a variation on the latter, determined by the fact that the shared element is a term instead of a whole proposition. They may involve either (i) two disjunctive premises or (ii) a conditional and a disjunctive premise with one term in common (in the latter case, with a conditional minor). An example is given at Nağāt 82, xx.
