Conditional perfection (CoP) refers to the phenomenon where a bare conditional sentence (if p, q) receives a bi-conditional (iff p, q) interpretation. This paper pursues two main goals: (i) to probe into possible grammatical factors (dis)favoring a CoP-interpretation of a given conditional if p, q; (ii) to shed some light on the crosslinguistic picture, checking whether the same grammatical manipulations are equally (ir)relevant for a conditional’s CoP-interpretation across two typologically unrelated groups of languages: Chinese on the one hand and English/German on the other. We consider three manipulations that are equally CoP-(dis)favoring in both groups, and two manipulations that seem to favor CoP only in English/German, but not in Chinese. The main finding is that some, but not all grammatical manipulations share the same pragmatic effect in the two groups under consideration.
