Etymology (PE): Izocand, from izo-, → iso-, + cand replacing candi (after prefix) “quantity,” from Mid.Pers. candih “amount, quantity,” from cand “how many, how much; so many, much;” O.Pers. yāvā “as long as;” Av. yauuant- [adj.] “how great?, how much?, how many?,” yauuat [adv.] “as much as, as far as;” cf. Skt. yāvant- “how big, how much;” Gk. heos “as long as, until.”
