Note 171 — EL CAPITÁN VENENO[4]
Reading edition
de saberlo = si lo supiese, if he knew it: the condition can be supplied in several ways: si lo supiera, a saberlo, sabiéndolo, si lo sabía, or even si sabe. The conclusion (here dimitiría) has fewer forms: dimitiera, dimitía, dimite, and rarely dimitiese. This form in -se is not considered good style.
