eum & eam - just a little history please.

I am looking for the root of ‘eam’ & ‘eum’ which I have run across in my reading. I have figured out the meaning of the words but I can’t find where they come from or anything aout them. Any info would be much appreciated.
Thanks,

They’re forms of the demonstrative is, ea, id. Is this what you were looking for? Or did you want more specific information on the history/formation of the word? In any case, you’ll find it easier if you search using the lemma (the dictionary form).

Thanks for the reply. All I need is a starting point but that previously escaped me, until now.
Thanks again for your input.
