And

and

When I say this word, does it not mean that "plus" - "this and that"? I have a computer monitor, an English dictionary and a telephone in front of me.

and

And yet it does not mean plus. See, I just used in in a non-plus sort of way.

My little Random House dictionary tells me that "and" means the following:

with or in addition to
as well as
plus or added to
then
then again
Informal, to: Try and do it
and so on or forth, and other things or the rest

and
Fine, I'll accept those defintions. I have to. In German we have und, in Italian e, in Spanish y, and in Serbo-Croat and is i.
Is it "Jack and Jill went up the hill" (two subjects, same action) or "I opened my eyes and got up"? What about "I ate and ate and ate, and at the end I was so sick"? Are these the same ands?
When I say "and", do I mean two (or more) things together, or am I, but way of using the "and", actually signifying a unity. Is "Jack went up the hill. Jill went up the hill." the same as "Jack and Jill went up the hill"?
