they have different purpose, maybe you missed this

ani lo shamati et ma she-hu amar - я не слышал то, что он сказал

alternatively

ani lo shamati ma hu amar - я не слышал, что он сказал


as demonstrative pronoun то/тот in Hebrew is hahu, та - hahi

tistakel, hine holechet ha-bahura hahi - смотри, вон идёт та девушка
That comment is perfect for my understanding, actually If those are really the definitions of то/та/тот then it's much easier than I thought. English dictionary did a disservice to me then, I needed a Hebrew-Russian dictionary for those!


Я думаю, что я видела как он играл в теннис на пляже

Американцы применили атомную бомбу, которая до сих пор вредит людям OR что до сих пор вредит людям (which is not very literal but understandable)


can you explain on what basis you decide where you're going to put что and where то?
On the basis of "whether LXNDR says it's correct or not"

I'm planning to use что for all purposes which just means "that" (in Hebrew "she", "ma")...

I'm planning to use то just for "that one" (in masculine form) (In Hebrew "hahu"), and та/тот with their genders accordingly

i think i figured out what your crux is

in Russian то is used to connect two clauses within one compound sentence only when their relationship is conditional and into English it translates as then or so

if you go, then i go too - если ты идёшь, то и я иду

you stay, so i do toо - если ты остаёшься, то и я остаюсь

here то is interchangeable with тогда which literally means then in English
Ohh...so то has more definitions!? Yikes!

Thanks for letting me know! Any more definitions for то I should be aware of?

ani lo shamati et ma she-hu amar - я не слышал то, что он сказал
BTW if we translate it word by word....


ani (Я) lo (не) shamati (слушал) et (что) ma (что) she-hu (то) amar (сказал)... and according to you - я не слышал то, что он сказал


so if I turn it into math, 2 times что followed by то becomes то, что... little wonder why so many russians are mathematicians and engineers!

J/K-- I know I am being too literate in my comparison of languages....
