Dear Nina,

"refuting with dhamma" or "refuting with reason" are other
possibilities. I was unable to find "saha dhammena niggayha" anywhere
else on the CSCD disk but there is something that comes fairly close
to it in the Mahaaparinibbaanasutta at D II 104:

...uppanna.m parappavaada.m saha dhammena suniggahiita.m niggahetvaa
sappaa.tihaariya.m dhamma.m desessantiiti.

At Sv II 552, Buddhaghosa explains "saha dhammena" with "sahetukena
sakaara.nena vacanena".

dhamma? The

I'm not clear at all about the
phrase "samaya~n~nuupamaahi.msaadiisupi dhammo". The "aado"
in "kaara.naado" indicates that there are other meanings of "dhammo"
besides the 14 given at Abh 784 and I would think that the .tiikaa is
providing some of those additional meanings but "samaya~n~nuu" etc.
just doesn't make a lot of sense here.

Other lists may have "hetu" or "paccayo" instead.

See above.

I don't know enough about this to give any satisfactory answer. The
same five kinds of knowables are also listed in the Saddaniiti, p.
604 but I haven't come across anything that explains them in any
detail. I think "lakkha.na" would include specific characteristics
(hardness,etc.) as well as the general ones.
