Notes :Burrow & Emeneau tentatively suggest an IA origin for the root (Old Indian sañcaka-, Panj. sañcā, saccā "mould"). This is highly unlikely, because inlaut -c- suggests a recent borrowing from one of IA dialects where *-ñc- > *-cc-; on the other hand, the ubiquitous dropping of the initial sibilant suggests a very old borrowing. Proto-Dravidian origin (with an old meaning like "mould" - not necessarily for casting iron) is thus more probable at the moment. // Present in 2/6 branches.
