Dear Yong Peng,
Thank you, I am also glad this is on again.
This prompted me to look up Warder Ch 23: agent nouns.
See below.

N: I would like to suggest: there are no killers...
As to ghaatetar: ghaateti: to slay, kill, destroy. The stem is on -tar, but,
declension: as teacher, satthar:
satthaa (nominative), satthaara.m (acc), satthaaraa (instr), satthu (dat.)
etc.
Y: sotar: a hearer.

> saavetar: ??a speaker, an announcer.

N: from a causative: causing to hear, reciter: nominative: saavetaa, etc.
Y: vi~n~naatar: a perceiver, a learner.

> vi~n~naapetar: an instructor, teacher. Verbs on -peti: causative. he causes

one to know.
N: all these words on- tar have a similar declension.
Without your sentences and Warder I would easily forget.
Nina.
P.S. Also your main website is very good and easy to use.
