> "sysati" "to hiss" (pol.syczec, syk- not sus). Hence another name1. With all my respect to Bruckner, su_s- looks like an odd cognate to Slavic *sys-. How would you explain the fact that RUKI rule doesn't work here if second *s is from *s, not from *k^? Onomatopoeia? Too easy an explanation: if the root has sibilant in there, then it can well denotate hussling etc.
